What Uninstalling the App Does NOT Remove

Uninstalling Comfy Desktop only removes the launcher app itself. The following data is not removed and must be deleted manually if you want a complete cleanup:
DataDefault LocationDescription
Installations%USERPROFILE%\ComfyUI-InstallsEach ComfyUI installation you created (can also be deleted from within the app). Custom install paths are also not removed.
Shared models & outputs%USERPROFILE%\ComfyUI-SharedShared model library, input/output directories
App settings & registry%APPDATA%\Comfy DesktopSettings, installation records, logs
The directories listed above contain your personal ComfyUI data — models, outputs, settings, and installations. They are not Comfy Desktop application files. Deleting them will permanently remove your data.
To fully remove everything:
  1. Delete the app data folder – %APPDATA%\Comfy Desktop
  2. Delete individual installations from within the app, or manually delete %USERPROFILE%\ComfyUI-Installs
  3. Delete the shared model library at %USERPROFILE%\ComfyUI-Shared (only if you no longer need these files)
