NSWorkspace does not seem to allow undoing said file operation (or any
file operation for that matter). Correct me if I'm wrong.
So I might have to figure out where the trash directory for a given
volume/user/file etc is and move it myself. Is there an easy way to
find that out?
Drop-dead simple. FSFindFolder is your friend. Give it a volume
reference number and tell it you're looking for the user's trash and
it'll hand it back to you (creating it if necessary and you asked for
that behavior).
I think possibly a bigger issue here is going to be that moving files
to the trash can cause them to be renamed. At least doing so in
Finder can; I'm not sure if the NSWorkspace routine does the same.
You'll need a reliable way to track the file and map that back to the
original location and name. You'll want to look at aliases for that.
