Bram is the Batch Renamer and Mover. It is used to batch rename files, as well as move them or copy them. You can work with one folder of items, or include its subfolders' items as well. There are many different ways you can renames the files, including dynamic parts that are unique for each file. It's got an easy to use interface that will be familiar to anyone who has ever used the Windows file explorer. Bram also makes use of multithreading when it performs the renaming operations, so it's efficient! And if you make a mistake, it's as easy as pressing the undo button to undo the changes that you made! All of this functionality, and more, is contained in a file that when installed is only about a megabyte! You can't go wrong with Bram!
