ReNamer is a very small tool for renaming files on a massive scale. The program offers all standard renaming procedures, such as adding prefixes, suffixes, complete renaming of files, numbering, character resizing and more. The application can also remove free spaces in the name, add sequences of numbers, remove numbers and characters, change file extensions and much more.

In addition, ReNamer recognizes Meta labels such as ID3v1, ID3v2, EXIF, OLE, and can rename folders.
