FAQ

Do I need both Dokan and WinFsp?

No. CHDMounter is a single executable; choose the mount core in Settings → Mount core. On Windows, Dokan is the default but you can switch to WinFsp at any time. Linux and macOS always use FUSE (libfuse3 / macFUSE).

Does CHDMounter run on Linux and macOS?

Yes. The application is cross-platform (Windows, Linux and macOS, x64 and ARM64). On Linux it needs libfuse3 and /dev/fuse; on macOS it needs macFUSE.

Does CHDMounter modify my CHD files?

No. The image is opened read-only and the mounted volume is read-only.

Can I mount a CHD as a regular folder instead of a drive letter?

Yes. Pass a folder path as the mount point, e.g. CHDMounter game.chd C:\Mounts\game on Windows or CHDMounter game.chd ~/mounts/game on Linux/macOS. When running elevated with WinFsp, folder mounts use a permissive DACL so standard processes can access them. On Linux/macOS folder mounts are always used.

Which console type should I choose if I am unsure?

Try psauto for PlayStation discs, iso9660 for generic data discs, or isoraw2352 when an emulator (xemu, RPCS3) wants a plain image.iso. See Console Types for the complete guide.

Why is the download bundle only a few megabytes?

The bundles are framework-dependent single-file executables: the .NET runtime is intentionally not embedded. Install the .NET 10 runtime once and all applications can use it.

How do I take a screenshot?

Press F8 while a CHDMounter window is focused. Images are saved locally — see Screenshots.

Where are my settings, logs and screenshots?

In the application data folder (%LOCALAPPDATA%\CHDMounter on Windows, ~/.local/share/CHDMounter on Linux, ~/Library/Application Support/CHDMounter on macOS), except screenshots, which prefer a Screenshot folder next to the executable. Use Help → Open AppData Folder to open the folder.

How do I reset the application to defaults?

Close CHDMounter and delete settings.dat (or the whole application data folder). The application recreates everything with defaults on the next start. See Settings.

Is the Tester application still released?

No. The CHDMounter_Tester batch-parsing/benchmarking tool is a Windows-only developer tool and is not published in release bundles. It remains available in the source tree — see the Development Guide.

Where does the update checker get downloads from?

CHDMounter checks the latest GitHub release of purelogiccode/CHDMounter and, when a newer version exists, links to the bundle matching your platform and architecture (win-x64, linux-arm64, osx-x64, and so on).

Do you collect diagnostics?

The application sends anonymous usage statistics once per launch and can send crash/bug reports when warnings or errors are logged. Known user errors (missing driver, wrong console type, busy mount point) are never filed as bugs, and test harnesses can never file reports. Logs and screenshots always stay local. See Privacy and Telemetry for the exact payloads and how to disable network access.

Can I use CHDMounter commercially?

CHDMounter is licensed under GPLv3. See License for details and third-party component licenses.
