Hey;
Just spotted a small bug (?) in 2.46. I'm trying to import/attach a cover file using a quick action. It fails for the following reason:
Import cover from file "S:\nostalgia 77 - soul jammin' 1\folder.jpg": File S:\nostalgia 77 - soul jammin' 1[ SYNTAX ERROR IN FORMATTING STRING ] cannot be accessed.
The workaround is to remove ' sign from the folder name. Hmmm... Looks like escaping special chars? 
Cheers!
