Right now, my command-line tool errors out if the destination filename, chosen automatically from the NSURLResponse object, already exists in the working directory. Should I keep it that way, or put the new file there anyway? If the latter, this involves doing something to the previous file with that name (or keeping it the same and renaming the new file instead). Should I delete the old file (causing problems if transferring the new one fails), try replacing (does it work across volumes), or trashing the old file (does this send the instant-delete GUI alert if it happens while current Trash items are emptied)?
If renaming is the answer, is there any sample code to do this safely, taking care of all cases? (For example, replacement name already taken, or adding an extension if the file doesn’t start with one, etc.)
