All files stored in the vault just as random file names (d\2E\PRSI6Q3ZASLMAHGQNFVVSDO66NYXXO). If I have deleted one file in the opened vault how to know which of the fault files I have to restore?
Is there a mapping table
real file name - fault file name?
Restore them from your backup.
Or if you are using Cryptomator with an online storage provider which offers a recycle bin, then you can restore the latest deleted files there also.
Or you are trying this (don’t know your operating system)
