    🧹 Cleanup Tools

    Before running cleanup, the app can show a preview of what will be removed. This gives you a chance to review the selected actions before anything is deleted.
    Cleanup actions are blocked while Microsoft Flight Simulator is running to help avoid file access problems or unwanted simulator behaviour.

    🪟 Windows & System Cleanup

    Available system cleanup options include:

    • Windows temporary files
    • DirectX shader cache / D3DSCache
    • Windows Prefetch, optional

    🎮 GPU Shader Cache Cleanup

    • NVIDIA DXCache
    • NVIDIA GLCache
    • NVIDIA ComputeCache
    • NVIDIA LocalLow cache locations
    • AMD DxCache
    • AMD DxcCache

    🛡️ Backup & Recovery

    MFS Cleaner / Fixer includes a central Backup & Recovery area for important simulator files.
    Supported backup types include:

    • Content.xml
    • exe.xml
    • UserCfg.opt
    • DLSS files

    Backups are created automatically before supported changes where possible.
    From the Backup & Recovery page, you can:

    • Restore individual backups
    • Inspect backup contents
    • Delete old backups
    • Manage existing backup files

    Existing backups are preserved and migrated where possible, so older backup files remain available after updating the app.

    🎮 DLSS Manager

    The built-in DLSS Manager supports both MSFS 2020 and MSFS 2024.
    It can:

    • View the currently installed DLSS version
    • Download DLSS versions
    • Verify downloaded files
    • Check integrity/checksums where available
    • Back up the current nvngx_dlss.dll
    • Install selected DLSS versions
    • Restore previous DLSS backups

    DLSS changes are blocked while Microsoft Flight Simulator is running.
    Please note that DLSS swapping is not officially supported by Microsoft Flight Simulator, so this feature should be used at your own risk.

    ⚙️ Startup Manager

    The Startup Manager helps manage applications launched through exe.xml.
    This is useful for controlling add-on launchers, external utilities and other tools that start with the simulator.
    The Startup Manager can help you:

    • View startup entries
    • Enable or disable startup applications
    • Back up exe.xml
    • Restore previous exe.xml backups

    🖥️ MSFS 2024 Settings Editor

    The app includes an MSFS 2024 Settings Editor for supported graphics and traffic options.
    This gives you a simpler way to adjust supported simulator settings without manually editing configuration files.
    Backups are created before supported changes where possible.

    🔎 Simulator Installation Detection

    MFS Cleaner / Fixer supports common MSFS installation types, including:

    • Steam
    • Xbox app
    • Microsoft Store

    It also reads UserCfg.opt to find custom package locations, which is useful if your simulator packages, Community folder or Official folder are stored outside the default Windows location.

    📊 Results, Logs & Reports

    After running actions, the app shows detailed results so you can see what happened.
    Results may include:

    • Deleted files
    • Skipped items
    • Failed items
    • Backup actions
    • Restore actions
    • Warnings

    Failure reports can be copied and shared when asking for support.

    🌍 Languages

    The interface currently supports:

    • English
    • German
    • French
    • Spanish
    • Hindi

    ⚠️ Important Content.xml Warning

    Deleting Content.xml may cause Microsoft Flight Simulator to reset enabled or disabled add-on states.
    Community and Marketplace add-ons are not deleted, but you may need to open Content Manager inside the simulator and re-enable the add-ons you want to use.
    Use this option only if you understand what it does.

    ⚠️ Advanced Optional Actions

    Some options are marked as advanced because they may affect add-ons, settings, licences or simulator behaviour.

    MSFS 2024 WASM Cleanup

    The app includes optional MSFS 2024 WASM cleanup.
    This option is:

    • Disabled by default
    • Clearly marked as advanced
    • Protected by a warning dialog

    WASM cleanup may reset settings, licences or activation data for some add-ons, including tools such as //42 Flow Pro.

    Only use this option when troubleshooting and when you understand the possible side effects.

    ▶️ How to Use

    1. Launch the app
    2. Let it detect your simulator installation
    3. Choose the cleanup, DLSS, startup, backup or settings tool you want to use
    4. Preview cleanup actions where available
    5. Run the selected action
    6. Review the results
    7. Use Backup & Recovery if you need to restore anything

    Some actions may require Administrator permissions. The app will tell you when this is needed.

    🛡️ Safety Notes

    MFS Cleaner / Fixer is designed to be careful by default.
    It:

    • Focuses on safe cache cleanup by default
    • Does not directly delete Community add-ons
    • Does not directly delete Official packages
    • Creates backups before supported changes
    • Blocks cleanup and DLSS changes while MSFS is running
    • Clearly marks advanced actions
    • Shows warning dialogs for risky actions
    • Provides detailed logs and copyable failure reports

    However, any cleanup or file-management tool should still be used responsibly. Always review the selected actions before running them.

    🧠 SmartScreen & Antivirus

    Some builds may be unsigned, so Windows SmartScreen may show a warning.
    To run the app:

    1. Click More info
    2. Click Run anyway

    This does not automatically mean the app is unsafe. It usually happens because the build is unsigned or not widely downloaded yet.
    You can verify downloads using the provided checksums where available.

    💻 Requirements

    • Windows 10 or Windows 11, 64-bit
    • Microsoft Flight Simulator 2020 and/or Microsoft Flight Simulator 2024
    • Self-contained .NET 8 build, no separate .NET install required for the packaged version

    💬 Support & Community

    A Discord link is included inside the app for help, updates and feedback.
    If something looks wrong, please share the app log or copyable failure report when asking for support. This makes troubleshooting much easier.

    ⚠️ Disclaimer

    Use at your own risk.

    This tool is designed to clean caches and manage selected simulator files, settings and components.Advanced actions, DLSS swapping, configuration edits and cleanup options may affect add-ons, settings, licences, visuals or simulator stability.
    Always make sure you understand the selected actions before running them.

    Saved me so many nerves with WASM crashes and improved the performance. After every AIRAC/Navigraph update, I run this to clean the old residual files, so no more WASM crashes. Must have app!

    Thank you so much! Really pleased to hear it’s helping with the WASM crashes and performance, especially after Navigraph/AIRAC updates 😊✈️

    That’s exactly the sort of problem I wanted MSFS Fixer to make less painful, so it’s great to know you’re getting good use out of it.

    Really appreciate the feedback and the “must have app” comment! 🙌

    Solid Tool That Does What It Should

    I've been using MFS Cleaner & Fixer for a while now, and it works really well for me. It does what it promises – cleans up unnecessary files and helps keep things organized. The interface is straightforward and easy to use.

    After running it regularly, I've noticed that it genuinely helps maintain performance and stability. No issues so far, and it's become a reliable part of my maintenance routine. For me, it's a good tool that I can depend on.

    should i use the main download or the portable download?
    craigybabyjAuthor

    4 months ago

    Either way works. If you want shortcuts and a proper install, use the installer. If you just want to run it without installing anything, use the portable self-contained version.

    Historique des versions

    MFS Cleaner/Fixer v1.5.7 A new Fixes tab, a new logo and icon, and a full visual refresh of the app. New: Fixes tab Content.xml health check scans the chosen sim’s Content.xml for corruption and duplicate package entries, then offers a backup-first repair (duplicates removed keeping the newest entry; corrupt files removed so MSFS rebuilds them). Fix stuck loading sets the chosen sim’s Community folder aside (nothing is deleted) and clears only that sim’s caches, then tells you what to try next. Restore Community appears afterwards and moves your add-ons back. Safe reset UserCfg.opt (MSFS 2024) backs up the file, resets video, graphics and traffic settings to the sim defaults, and keeps your InstalledPackagesPath. Each fix has its own simulator dropdown, so large Community folders on other sims are never touched. Results show in the left panel while a fix runs. New look New MFS Cleaner/Fixer logo in the title bar, with the news ticker and window buttons on the same row. The ticker fades at both edges and no longer shows a lone “RSS Feed:” label before headlines load. New app and installer icon, plus a branded installer sidebar and header image. Dark themed dropdowns replace the white Windows ones everywhere. Single-line tabs with an aligned underline; Backups now sits last. One colour system: shared surface, border and text-tier colours, matching card padding and corners, a subtle gradient on primary buttons, tonal mint for in-card actions, and soft radial background glows. Small uppercase section labels, monospaced file paths that truncate with a tooltip, dark tooltips, and Fluent-style minimise/close buttons. The Status block is docked to the bottom of the left panel on every tab, and the Log and Results boxes show a quiet empty state instead of a black void. Buttons share the same size and style on every page; the Cleaner’s small buttons are compact. A slim busy bar runs under the title bar while an action is working. Cleaner Live progress while a large folder such as Temp is emptied: a running item count in the status line and the log, so it no longer looks stuck. Items that could not be removed because they were in use or protected are reported as “left alone” rather than “failed”, and the Copy Failures button is now Copy Details. The Run Selected Actions review appears about seven times faster, shows “please wait” while it prepares, and the buttons lock until it is ready. Partner links Added Global Vectors (independent ETS2 multiplayer) under BeatMyLanding, both in matching cards with the sites’ own logos. Buy me a coffee is now a yellow button drawn by the app instead of a downloaded badge; language flags are bundled with the app and sit in a pill with a hover highlight. Fixes The backup list no longer flashes white while it refreshes. Safe reset UserCfg.opt only offers MSFS 2024 installs.
