Don’t know about you, but quite often we need to rename a lot of files at once. Sometimes we are adding a serial number, other times we need to eliminate characters, or add a prefix or suffix. It used to be a real chore till our stock agency (Masterfile) turned us on to RName. It was freeware for Mac. But sadly it is no longer available. Luckily someone else is making a very similar if not better program called Renamer4Mac. There is also some freeware for Windows called Rname-it.
This is not software that we use everyday, but when we do use it is it a total life saver (not to mention, time saver!) One of the biggest uses we have for this is our stock agency demands a certain naming convention that is very different than our in-house naming system, and theirs makes the file name very long with a lot of characters that serve no purpose for us. But with these renaming programs we can just prep all of our files, drop them into the program and batch rename them all at once while still retaining our original file name within the new naming convention, so that we can always refer back to the original file, should we need to.
Again these are all freeware programs (free download) and great utilities… check `em out!
