What is the best way to make a copy of a file and then continue to work with the original? Hazel's behaviour is to my mind a bit counterintuitive in that it will 'follow' the copy and continue to work with that.
My scenario is to back up a file externally before doing anything further to it. One way is to make a copy and then copy it back. Unnecessary round trip, not ideal.
My current solution is to move the file to an intermediate folder and then do the backup copy. A second Hazel rule then monitors the intermediate folder and runs the next actions from there. Works, but just seems rather awkward.
Using this technique I have 9 folders to perform actions on my incoming files, where only 4 are really needed. So I was wondering if there is a more effective way to do this? Or anything I've missed?
Any info appreciated, thanks.
