Hi ​@Marcaplus

Welcome to Box Community, and we’re glad to assist! 

Deleting Box Drive’s cache folder can permanently remove locally stored content that hasn’t been uploaded and cause loss of unsynced edits. 

 

If you must clear your local space from Box Drive’s cache folder then you should safely delete your cache folder. To do so, you should manually reset your Box Drive application. 

 

 New Version - To reset Box Drive on Windows 

  1. Exit Box Drive (if it is running). If necessary, use Task Manager to end the Box.exe process.
  2. Run command
    “C:\Program Files\Box\Box\FS\cf\cfctl.exe" drive reset Box
    on command prompt. Files not uploaded to Box will be saved to the Desktop with a timestamp.
    1. The output should say “Box Drive reset completed successfully” at the end. If this is not so, then it may be that some files were still open and could not be deleted. Once everything is closed, a re-run of step 2 should be successful.
  3. From RegEdit, delete the registry entries under HKEY_CURRENT_USER/Software/Box/Box to clear Box preferences.
  4. Restart the Box Drive and follow the prompt to log back in.

If you are still having trouble, open a support ticket.

 Legacy Version - To reset Box Drive on Windows 

  1. Exit Box Drive (if it is running). If necessary, use Task Manager to end the Box.exe process.
  2. Ascertain whether any files exist in C:\users\[USERNAME]\AppData\Local\Box\Box\unsyncedFiles. These are files that have not been uploaded to Box. If these files do exist, and if you want to keep them, copy them to any location outside of C:\users\[USERNAME]\AppData\Local\Box\Box\ (such as your desktop). Proceeding with the steps below deletes these files.
  3. Delete this folder: C:\users\[USERNAME]\AppData\Local\Box\Box.
  4. From RegEdit, delete the registry entries under HKEY_CURRENT_USER/Software/Box/Box to clear Box preferences.
  5. Restart the Box Drive and follow the prompt to log back in.

Aside from this, you could always control the cache folder limit and set your cache folder limit

 

Hope it helps, and please let us know if you have more questions.
