Some tasks are just harder than they should be, and renaming a large number of files is one of them. Sure, if you’re a command-line whiz, you might be able to use grep to do this, but for the rest of us, a utility like Name Munger from Sonora Graphics is just the ticket. With it, you can replace text in file names, add prefixes and suffixes, remove one or more occurrences of text in names, strip characters, change the case of names and extensions, and number files consecutively. Even with a graphical interface, getting everything right can be hard when you’re working with text patterns, but once you drag the files you want to rename into the program, Name Munger shows you a live preview of what your current settings would do. I won’t pretend it’s something that everyone needs every day, but for only $10 (along with a discount for entrants), Name Munger can pay for itself with only a few uses.
