Hello people,
I know similar issues relating calbin popped up here and there, but I did not find a thread similar to mine.
All daily work seems fine, but deleting ebooks. Well maybe I did not delete an entry for some months

Anyway I get "OSError: [WinError 50] request not supported" (<- I translated that from German) and yes I am having my library stored on my NAS. I am aware that this is not supported, but it has been convenient for me for more than 10 years. I am using calibre since 0.x
Actually till some hours ago I had "\\192.168.10.1\private" mounted to N:, so it said smth like 'N:\\calibre\\.caltrash'. I was trying things left and right.
The issue only happens when deleting it seems. So it might have smth to do with the escaped backslashes (double backslashes)?!
Acutally now I downgraded to 6.12 (before calbin was introduced) and all works fine again.
I am a programmer myself for decades and I know how tiresome it can be to cope with people using unsupported stuff -- sorry :/ --, but in this case I got the feeling that it might be an other issue and not related to network/filesystem stuff.
Below I attached the error trace.
Any comments?
Thanks and regards
Axel
