ReNamer is a free portable Windows tool that allows you to rename multiple files at once. It is easy to use because it offers specialized rules for every possible file renaming scenario (see options with screenshots below).

Rename Multiple Files - ReNamer

You can simply drag and drop files and folders to the ReNamer interface. This allows you to rename multiple files at different locations in one go. You can also apply multiple file renaming rules at once.

Probably the most important feature of ReNamer is that you can preview the results before actually renaming multiple files. I recommend the use of this function always because reversing the renaming of multiple files is often quite difficult.

I tried the installable version of ReNamer on Windows 7 and the portable version on Windows PE 3.0.
