Hi there!
Some time ago I deleted Folder with Another folder inside with Files inside from BoxCryptor directory.
Trash was enabled in BoxCryptor Preferences.
So now files in Trash these folders and files are locked so I can't empty Trash (in Finder) or do something else with it:
«The operation can’t be completed because the item “2013” is in use.»
If turn of BoxCryptor the folder is not shown in Trash.
I tried to reinstall boxcryptor, to unlock files, but nothing work.
I have Boxcryptor 2.3.405 (746) and macOS 10.12 Sierra. The problem was on previous version of macOS too.
Please help.
