@oeci @oggy512 What office version are you using? (standalone or within the office 365 bundle, 2019/2016) And what is your installed Dokany version?
I tried to reproduce it with Microsoft Office 2016 and Google Drive, but were unable to do so. The temporary ~$ files were deleted and I only noticed their creation/deletion because Google Drive asked me if these files should have been really deleted. Maybe your Google Drive settings are causing this. But maybe i got the wrong office version.
You can provide log files the following way:
- Activate Debug logging
- Create a fresh/empty vault
- Restart Cryptomator
- Unlock this new vault (only this!)
- Reproduce this bug/“left-over” file
- Lock the vault and close the application
- Upload the log file with Firefox Send and send me a PM with the link
