In rare instances Box Drive fails to launch. Manually resetting Box Drive can often resolve this.
To reset Box Drive on Windows
Exit Box Drive (if it is running). If necessary, use Task Manager to end the Box.exe process.
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.
You may need to show hidden folders to see \AppData.
Delete this folder: C:\users\[USERNAME]\AppData\Local\Box\Box.
From RegEdit, delete the registry entries under HKEY_CURRENT_USER/Software/Box/Boxto clear Box preferences.
Restart the Box Drive and follow the prompt to log back in.
Navigate to your ~/Library folder: In Finder, click the Go menu, press and hold the Alt (Option) key, and then click Library.
See if any files exist in ~/Library/Application Support/Box/Box/unsyncedFiles. These are files that have not been synced (not uploaded to Box). If these files do exist, and if you want to keep them, copy them to any location outside of ~/Library/Application Support/Box/Box/unsyncedFiles (such as your desktop) before proceeding with the steps below, which will delete these files.
Open a Terminal window and run the following command:
This command will delete Box Drive preferences and application data
Restart Box Drive and follow the prompt to log back in.
Once you restart Box Drive, you can review any archived unsynced files (File Provider Extension mode) or unsynced files you moved elsewhere (kernel-based mode) and either upload them manually or delete them to free up hard drive space.
