How to delete pictures which have been removed from the library?
Please describe the problem you are trying to solve
In Shotwell, when deleting photos the user is asked if the photo is to be "removed from the library" or "removed from the library and also moved to trash". By mistake, I picked the first option: Hence the pictures are still all on disk! My question: How can I move pictures which are not in the library to trash?
Other solutions you have considered
I can do this by hand, going through each directory (one for each day...) and checking each picture...
