Say I'm processing a series of files, making similar but not identical changes to each file. I'll probably have a source directory and a destination directory that's common throughout the sequence of operations. These directories might be on different drives and with differing levels of hierarchy. This necessitates a relentless repetitious sequence of mouse clicks as I change from input file locations\ to output file location.
It'd be useful if PS could learn what I was doing and helped me out here. Perhaps before I started, I could identify the two locations and PS could remember and use them automatically until I told it to stop.
