Could not restore corrupted library due to NotADirectoryError

[hinyarii]

Hi all,
Just turned on Calibre today on my thumbdrive and found out my library was corrupted, in-built repair feature doesn't seem to work. I suspect I might have turned off my PC w/o ejecting one day and that corrupted it. Been trying to fix it but to no avail. Searched online for the error I got but can't seem to find anybody else that has faced this issue; ok with sending my library if it helps w troubleshooting.

Wld rly appreciate if anyb here knows how I can fix this, as it contains a lot of my files. Thank you!

calibre, version 7.12.0

delete the desktop.ini file references in the error message and you will be fine.

Hey, thanks kovidgoyal, seems to have fixed that error. Ran into a new error though:

calibre, version 7.12.0
ERROR: Failed to repair library: Restoring database failed, click "Show details" to see details

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Sorry to bother you again, and thanks so much

Try doing the restore in safe mode or alternately run it via the command line

calibredb restore_database -r
