FileUtils

With this multi-tool of file utilities you can merge, split, rename, replace text, Swap bytes, convert line-feeds, and Compare Files. Most of these utilities can operate on multiple files at once, making it easy and fast to do otherwise tedious tasks like renaming files or replacing text in a bunch of files. You can also add shortcuts in the application to external programs that you use often. With FileUtils you have a bunch of useful tools in one program, just like a Swiss Army Knife. Version 2 includes three New Utilities: HexEdit, Grep and WordCount.
