The first thing you'll probably do when trying this tool for the first time is move your currently installed addons outside of your 'real community folder' to put them in your new 'custom addon folder'. To avoid problems, please try first with a single addon only to make sure everything works fine for you.It would be sad if you move 200GB and then you notice it does not work for you. Files placed directly in the new folder should always work but, for some users (not the majority) the files moved might get encrypted if you have the MS-Store version so it's worth checking before. Thank you.


note : for the detailed changelog, please check the 'changelog' tab at the top of the page, below are just general informations

Addons linker / Addon linker

** added 2021.06.06 **

new version, finally a little map for all those who requested it, hopefully some of you will find useful.

Please check the what's new (changelogs) for info on how to use the map (it's simple but still 2-3 things to know). I also added a little head up towards another addon manager that you might find interesting.


** added 2021.03.13 **

a new very well done video by badGamr has been posted on Youtube

It's based on the latest version (as of today) and covers most of the features, a must see if you need some help or are starting with the tool or have some questions about it

Many thanks badGamr !

** added 2020.10.24 **

** added 2020.10.13 **
little video to get you started with the tool made by lostboii, many thanks to him


Another little addon manager. Made to match my own needs and just sharing with the community.

I tried to keep the UI very simple but it should hopefully do the job 'feature-wise'.

- lets you organize your addon freely in folder and subfolders in your folder of choice
- will create links in the community folder. There is no need to move files in and out of the folder.
- very easy to activate/deactivate groups of addons (single click)
- lets you save presets of addons
- lets you rename addons (link will be automatically updated)
- lets you add / update / remove addons

Installation :
- just extract all the files and drop them in a folder of your choice and run the EXE file

usage :
- create a folder where you will put your addons, add your addons in there instead of putting them in the community folder, you can create as many subfolder as you want to organize your files efficiently
- launch the application, in the options screen set your 'addon folder' and your 'community folder'
- just click on the checkbox to activate/deactivate addons
- rest should be fairly easy to understand (little quickstart guide should be coming soon if needed)

notes :
- if it doesn't work please try to set the application to run as admin, if it works but you still get the message at the start, just disable the message in the options screen
 -i was made aware that other tools seem to do pretty much the same things but probably with some differences (have not tested them though because i learned about them after mine was released last week), anyway each has probably its own advantage and it's just free and just for fun, so you can freely decide to use mine if you find it useful.

big thanks to the guys in the AVSIM forum that helped me testing the very first versions with feedback and ideas. I will now post it here exclusively making it easier to maintain for eventual updates.

Thank you

Amazing tool, extremely helpful for organizing my hundreds of add-ons! Really appreciate you making this available

If I have any request, it would be nice to be able to filter the right side list to see only the invalid links so that I can address them quickly. But that's just a suggestion.

Hello, I can't open it. The icon will appear after double clicking, but no program will be displayed

this is not working anymore for me. i been using it for a year now. its my go to love it. i did not change or add anything. was working yesterday, now it wont start the sim



9 day(s) ago / Remercié par bad2000

Been using more or less since release - never left a review, but its time i did. I couldnt see me without this now if i am honest. I love having everything organised and sorted, and easy to enable/disable. I have folders such as Airports/USA,UK,South America etc - Something similar with scenery add ons and liveries. Excellent ability to sort and micro manage. Thank you, keep it up.

Excellent program and I'm still recommending it

Yesterday, after a few flights in the morning with this linker, which was working awesomely for a few years now, suddenly crashed and crashed, CTD. I got your latest update, is there a fix for this?

I ste this up with a desktop folder for my addons, and then realized after moving a dozen of them that I didn't want that folder on my C drive. So now I have a dilemma - how do I move those files to the D drive? Can I reverse move the files back into my Community folder and start over? Or can I move the folder from my C drive to my D drive?

Hi, Amazing tool, well done!!!

I see the option to open other apps in High priority, can the same be done with the Sim itself?



16 day(s) ago / Remercié par bad2000

Absolutely great!!! Since MSFS is growing and does consume more and more of the system drive C: It your addon-linker is an absolutely must-have tool for me to manage community contents and transfer it to secondary drives. Thank you, great work!!! For testing purposes on problems with new addons it is great too.

Hi Bad2000,

I have a lot of mods that replace the Official files (the majority for change officials aircraft.cfg, model.cfg, or .xml files). I active them using your awesome program through Community folder like all other addons.

But when the sim updates, i need to compare manually the filesize of each Official file to see if they change something new. If they have different size than the size I saved before update, they have changed and the mods are missing some new code.

Could be possible to add a Tool called for example "SU compatibility..."? The interface could be for example the same as the current "Preset Editor". It could easily compare the files and tell you what mods could not be compatible with the update.

It could work selecting all the mods we want to use with this tool and pressing a button "Save mods version". The tool automatically reads what files are invoved and stores the filesize of the Official files with the same name. It also stores the actual sim version. The official filesizes and sim version could be stored at the current "/Addons linker/Data/". And the next time the sim updates, we can easily press one button "Check compatibily" to see what mods could not be compatible. So we could avoid crash our sim, or miss some updated features.

I think it would be an awesome feature usefull for all the community. Thanks for all, cheers 😊

In your last update, a pulldown menu has been added to the right side. By default it says "- Keep current selection -" but how can I see WHICH selection is currently being kept? I understand that if you open that pull-down menu you can choose a different preset, but when reloading Addons Linker I don't actually see the preset I selected before listed anywhere and I always start to doubt the right preset.

Maybe I'm overlooking something?

Of course nothing but good about this great addon which I have been using since the beginning. I am grateful to you for your tireless efforts to bring it to what it is today.





22 day(s) ago / Remercié par bad2000

Great mod thanks! But pleaaaase, how do you uninstall it? I've some issues and I'd like to return to the default community folder configuration for some time and test things.

Bonjour Monsieur bad2000.

Un GRAND MERCI pour cet utilitaire qui est SUPER UTILE.

J'aimerais faire un petit don pour vos efforts et l'attention que vous portez aux questions des utilisateurs.

Pour ma part, je n'ai pas encore eu besoin d'en poser car j'ai trouvé dans la FAQ et dans les réponses détaillées que vous faites.

Donc, ma seule question est: comment faire ce don pour vous remercier ?

Grand Merci encore.

Translated with

Hello Mr. bad2000.

A BIG THANK YOU for this utility which is SUPER USEFUL.

I would like to make a small donation for your efforts and attention to user questions.

I, for one, haven't had to ask any yet because I found in the FAQ and the detailed answers you do.

So, my only question is: how to make this donation to thank you?

Many thanks again.

Is there a way to exclude a folder from the "something about your add-ons has changed" detection? I use Little Navmap to write a copy of my flight plan to a subfolder of the PMS50 GTN750 add-on, to be able to import the file in-game. This makes MSFS Addons Linker think that something changed about my add-ons (while that's technically true, it's misleading), and I have to click the "Refresh folder" button, because OCD.

Hello Mr Bad,

Thanks for a great free product.

Recently i have gotten the invalid key message when on the map page. I have my own key and it still says invalid. i made three more keys all invalid. could you advise what im doing wrong please?

Also, is there a way to select to enable addons in bulk for a certain country?



Just run into an issue...Now when I select a preset, USA for instance the interface does not show those add ons it continues to show the UK.

Terrific app...been using it since day one. Sadly, just updated to check out the new map part of the program and now when I run the exe as admin, all I get is a small taskbar notice that is blank but labeled Bing Maps? The main program will not start? Any idea or suggestions?



1 month(s) ago / Remercié par bad2000

gorgeus app. Anyway, why for certain addons , I can add the link, but I cannot remove it?

The app has a button to "Show All Selected" which works great, but from what I've seen, unless I missed it there's no way to save that option so when I exit and restart AL I'll see only selected items. I'd be fine if it was just an INI change to activate it. Thanks.

Absolutely love your addon linker! I'm running a very very old version of it and thought I would update it but was a bit nervous as to what I need to do for the update to work smoothly and not wreak havoc with the sim... 😊 Do I need to unlink everything in the current setup and uninstall the current version of the program before updating or do I just write over files in the new install?

Thx for any assistance! Currently running version 0.8.7722.27398

  • Version 0.18.8309.37 October 01, 2022

    A little hotfix for v18, sorry for those who had some troubles with it.

    [HOTFIX] potential crash at the start of the tool (happened to new users and users that had never created a preset)

    [HOTFIX] v18 introduced a degradation of performance in the dependencies and presets editor screen if you have tons of addons, it should be fixed now.

    [OPTION] there is a new option in the options screen to remove the counters appearing after the folder names (might slightly imporove performance if you have tons of addons)

    Thank you to the users who reported the issue and helped me resolved them !

    Here are the rest of the news for v18 to keep everything in this unique post :

    [NEW] 3 new 'Windows 11' based theme (1 light and 2 dark), please check them out (Themes are available in the options screen in the UI options tab). The 'dark mode' checkbox has been removed and replaced by the theme selection (old themes are still available)

    [NEW] Added a little preset selection list near the 'launch' sim button to apply the selected preset before launching the sim.

    [NEW] Added an option to automatically show the 'preset selection screen' when launching the sim. (options screen 2nd tab)

    [NEW] Added a new ICAO column in the main view and in the map grid so that you can search addons via ICAO. Note that to update the ICAO values, you need to use the scan icao function available in the Tools menu or with the toolbar button. The icao can be shown on the map dot label via an option in the otions screen.

    [NEW] New button in the toolbar (and main menu) to hide the 'community folder panel'

    [IMPROVED] finished the UI overhaul, main menu and contextuel menus are now also using the new resizable vector icons

    [IMPROVED] the scan ICAO (check duplicate) does not rescan everytime all addons anymore, only new addons are scanned. This lead to huge gain of time, if you want to rescan everything you can force a complete rescan by using the reset button.

    [IMPROVED] the scan ICAO (check duplicate) now also checks addons placed directly in the community folder or linked by other tools.

    [IMPROVED] The position and size of the preset, dependencies and documentation screens are now saved when the screen are closed and restored when opened

    [IMPROVED] Numerous color fixes for dark themes

    [MINI] Added an option to show the checkbox of the root folder. This might be useful if you have added several main custom addon folders and want to select all items inside in once click (options screen 2nd tab)

    [MINI] Added a new button in the toolbar for the 'scan ICAO/duplicate' option

    [MINI] Added a button in the options screen (UI options tab) to reset all windows position to their default value. This can be useful if you Window is restore outside of your monitor boundaries after some monitor settings change.

    [FIXED] Presets and dependencies editors were not showing the correct number of selected elements and the counter data was not updated when selecting/unselecting elements

    [FIXED] Presets and dependencies editors were not using the new red/green scalable vector icons and the paremetrized colors were not applied so it's was not matching with the colors in the main view

    [FIXED] several little changes/fixes here and there

    This version includes an update to some of the base components, make sure you replace ALL files when updating to prevent errors.

  • Version 0.18.8309.24 October 01, 2022


    ** replaced by HOTFIX **

  • Version 0.17.8301.27 September 23, 2022

    Hello, a little update for SU10 and some little requests filled, the other main goal of this version is to try to make it a bit easier on the eyes for those having big monitors (quite common with flightsimmers it seems).

    [NEW] Resizable UI toolbar/buttons/checkboxes. In the options screen you can now set the size for the toolbar items (will also increase buttons images and checkboxes) to make it easier to read on big resolution monitor. Use this new options in conjunction with the font size options and you should be able to get something that works better for you. Icon size is probably better at '24' for 2560x1440 resolution, '32' for 4K monitors. All this is available in the last tab of the options screen. Note that the menu icons are not changed yet. More info here ->

    [NEW] Map polygonal selection. This allows for example the selection of all addons following a specific flight plan in a few click. Right click and enable the polygonal selection, then click the succesive points to draw the shape of the selection, double click to close the shape and all addons inside the shape will be selected. Then use the enable option to enable them

    [NEW] You can now use the F5 key to refresh the main views without having to click on the buttons when you see the red indication 'refresh needed' at the top

    [NEW] You can now hide folders that do not contain any addons in the main view (options screen, 2nd tab). This is useful if you have other things than addons in your folder structure so that they wont appear in the view with all their subfolders)

    [NEW] The map can now show addons placed directly in the community folder if you enable the 'show official/onestore airports' in the options screen (3rd tab)

    [IMPROVED] Added a contextual menu on the ICAO checker list (save layout / delete addon / export to Excel)

    [FIXED] The documentation browser was not opening automatically the first document in the list when clicking on the open button

    [MINI] You can now open the manifest.json file directly from the 'edit custom data' screen

    [MINI] You can now specify the desired PDF reader to be used by the documentation browser if you have multiple readers (by default it will use the Windows default registered PDF application) (options screen 2nd tab)

    [MINI] ICAO checker now shows below the prograss bar which addon it is scanning

    [REMOVED] Content.xml editor is now removed, the stucture and usage of that file was completely changed with SU10 so the included editor is not useful anymore. I can probably add an editor for the new file but it's probably not needed anymore due to its new role. Note that the 'hidden feature' of auto deletion of the content.xml file when the sim is launched is also removed because it doesn't make much sense anymore

    [UPDATED] Updated simconnect library to the latest SU10 version

    [MISC] Several other little fixes/changes here and there

    There are a few more requests in the pipeline (like some sort of 'reverse dependencies' allowing to declare that an addon will conflict with another addon, or improving the ICAO capabilities adding that info in all grids and on the map) . If you asked for something that is important for you and i told you that was probably possible to add in the tool and you think i forgot about it feel free to msg me again (yeah this project is not really done in a professional way) ;)

    If addons makers are ready to supply a little file with their addon it would also probably possible to have the dependencies automatically set without manual intervention but that's probably a bit too much to ask.

    To Update : simply replace all files in your existing folder (settings will be kept).

    As always let me know if i broke something and i'll try to fix asap.

  • Version 0.16.8183.20 May 28, 2022

    Very small update to fix a few things and add a few more requests.

    [NEW] New 'Check for duplicates (ICAO)' option in the 'Tools' menu that will check for duplicate airports in your addons folders. Note that, as always, encrypted marketplace addons can not be checked, this is not something that can be bypassed. Not sure if there's interest, but if needed maybe i can add little option where you could enter manually the ICAO of those marketplace airports that you own so that they will be checked with the rest and appear in the result list if you have a custom addon for that same airport.

    [IMPROVED] The 'program launch feature' now includes a new option that allows you to launch an external program only when an addon is selected (for example launch AIG Traffic Controller' only when the 'aig-aitraffic-oci-beta' addon folder is enabled in the tool).

    [IMPROVED] you can now print the map if you want to (right click menu on the map the use the 'print' option, the visible part showing on your screen will be printed)

    [FIXED] fixed some colors issue when using custom colors or themes

    [FIXED] some more little fixes here and there

    As always, when updating, make sure you replace all files included in the zip and not only the EXE (some other files are changed from time to time and it's the case with this release)

    Thank you

  • Version 0.15.8156.23 May 01, 2022

    A mini maintenance release just to fix a few minor issues add add a few specific requests, and hopefully a useful improvement in the 'launch external programs' feature, see example pic -->

    [IMPROVED] Overhaul of the 'launch external programs' options. If needed, go through your existing programs and adapt the settings as needed (right click 'edit' to change the parameters for each program). Custom arguments, custom delays, waiting for simconnect, process priority and affinity can now all be set for each program individually

    [IMPROVED] You can now add custom folders to be scanned for the documentation browser, there is a little button at the top-right of the screen. (For example if you want to add your MD80 docs just add the 'C:\Users\<your_username>\Documents\Maddog X Files' folder as custom folder).

    [IMPROVED] You can now add/remove multiple tags at once via the new 'Manage tags for the selected addons...' right click menu option. Note that this needs to be improved to be able to remove 'tags', for now it just add tags, should be available in the future version.

    [IMPROVED] It's now possible to enter multi-line descriptions for addons.

    [IMPROVED] If you have multiple 'addons folders', you can now choose in the options screen if you want them to be sorted by 'name' or in the order you have introduced them in the options screen (note that this option has no effect if you have saved a custom layout that includes a sorted column)

    [IMROVED] If you have specified batch files in the auto-launch programs, the 'black command window' will not be shown anymore when executing the batch

    [IMPROVED] Custom description can now be used as map dots tooltip, the description column has also been added to the map screen grid.

    [IMPROVED] Some little improvements for the recently introduced new 'black' dark mode

    [FIXED] MaterialLib/ModelLib scanner could hang when reading a layout.json files containing errors.

    [FIXED] Documentation browser was sometimes not refreshing the documents list properly after applying a filter or doing a search

    [FIXED] The first item of the main view wasn't always properly selected and focused when launching the tool

    [FIXED] The renaming of the 'description' column had no effect if a custom layout was saved (via the option 'save columns/order size). The renamed column was also not renamed in the other screens (gridview / dependencies and preset editors)

    [FIXED] The 'Load preset' argument was not working properly if used at the same time as the 'startsim' parameter

    [FIXED] The usual little fixes here and there

  • Version 0.14.8141.41 April 16, 2022

    oh well yeah, i will never get it right the first time, so here is the little hotfix as usual ... sorry for that ;)

    [HOTFIX] new 'documentation browser screen' was not opening properly due to a little last minute change that was not tested on a PC without development tools

Foire aux questions

Des questions ? Trouvez votre solution ici.

How to install / update ?

Simply unzip all included file in the zip in a folder of your choice. For updating, repeat the same process after deleting the files that came with the previous version.

Will my settings be kept after an update ?

Yes, the settings are saved in a different folder (C:\ProgramData\MSFS Addons Linker). The presets are also stored in that folder by default but they might be in another folder if you changed their locations in the options screen (so make sure you don't delete them if you changed the location manually).

Can i save the columns order / size ?

yes, there is an option for that in the right click menu (save columns order / size). If you do that, the column order will be restored on the next restart of the tool

After launching the tool i see the icon in my taskbar but the screen does not show up (main screen of map screen), WTH ?

oops, the tool saves it's locations when closed. If you change monitor settings between 2 sessions (for example going form dual screen setup to a single screen setup) it might happen that the screen is restored outside of the boundaries of your current screen, so it will be there but you wont' see it :)

You can fix that easily by going to the configuration folder (C:\ProgramData\MSFS Addons Linker)

  • make sure the tool is closed
  • open the ini file (MSFS_Addons_Linker.ini) with notepad
  • remove the three lines starting with the text below (they are at the bottom of the INI file) :
  • save the INI file and restart the tool and it should be fixed

If you have the same kind of problem with the map's screen you need to remove this line :


On the next restart the app should show up correctly on your screen.

I'm getting 'can not read manifest.json file', addons do not work when moved outside of the community folder

This is unfortunately an issue some users having the MS-Store version faced. When addons are placed in the community folder they are somewhat encrypted (not exactly sure what Windows does). When you move them elsewhere, they don't work anymore. It seems to be a Windows limitation and there's not much we can do. For some users copying the addons instead of moving them fixed the issue but that doesn't seem to work for everyone. In the worst case you would need to redownload the addons having the problem and place them directly in your custom addon folder.

If you have the MS-Store version an plan to move all your files outside of the community folder, i strongly advise you to try first with a single addon to make sure it works. There are also some workaround you might try if moving doesn't work for you (feel free to contact me if needed).

I have a crash when .......

please send me a private message on this site (there is a little option 'private message to bad2000' in the action menu on the main addon page) with the detailed error message that you get. I'll do my best to try to fix

Can I apply multiple presets at once ?

yes, you can do that either by using the 'presets screen' available in the toolbar menu, in that screen you can select several presets and apply them at once. You can also use the button 'apply cumulative' at the bottom of the addons list. That button will apply the selection of the presets without removing the currently selected addons.

I get invalid links if i rename / remove addons via the Windows Explorer

this is normal because if you do operations via the Windows explorer the links can not be maintained (for renaming for example there is an option directly in the tool's right click menu, if you do that inside the tool the link will be maintained by the tool). Anyway if you get invalid links you can delete them easily with the right click menu 'delete invalid links' on the right panel (they can be spotted easily because they will be with a red background), then just recreate the link for the desired addon.

Where is the manual ?

there is none .. shame on me for sure ;) It should be fairly easy to use though and feel free to ask if you have any questions.

There are also some videos about the tool that have been popping up on Youtube, they can certainly help understanding the basics (many thanks to their authors).

Donations ?

Thank you very much about thinking about making a donation. I really appreciate that but it's ok, there's already so much stuff to pay for nowadays, just enjoy the little tool if you think it can be useful for you and don't worry about money.

How to uninstall everything / start new ?

To remove completely the application you need to remove two folders.

- the folder in which you unzipped all files

- the configuration folder that is created automatically when the tool is run for the first time and where your settings are saved (C:\ProgramData\MSFS Addons Linker)

if you do that it will be like if you had never installed the tool.

Do I really have to launch the tool 'as admin' ?

The real reply would be NO. But well, it's a bit difficult, the more precise reply is 'not anymore since v0.8' but YES if you have already used older version of the tool.

Unfortunately it was required for earlier version (because the tool was creating links that needed admin rights, now not anymore). The fact that it was required in earlier versions means that now your configuration files are saved 'as admin' and if you run the tool 'not as admin' you wouldn't be able to update them so you are pretty much forced to continue running the tool as admin. It's a bit annoying.

Feel free to contact me if you need more info and don't want to run it 'as admin' anymore because it would be as simple as recreating your configuration files without admin rights.

Why do some addons show up in red ?

The red color is just a warning (everything will work fine). It indicates that you have two (or more) addons with the same name in different folders. Those are probably duplicates that need to be checked.
