Recently I sometimes have the Problem that files are damaged.I copied an excel-file in the same folder using Ctrl+C and Ctrl+V.
When I try to open the copied file, I get the error-message that it is damaged.
For now, I couldn’t trust in Cryptomator if the files I added sometimes are damaged after a while.
Yes, the problems seem to be caused by Microsofts Upload Center. As you described, it shows the concerned file in “Speicherort”. If I deactivate the Upload-function everything works fine.
