Ant Renamer is a lightweight, open source software program for the batch renaming of files and folders. Along with being easy-to-use, Ant Renamer provides a massive list of flexible options for applying various renaming rules (ex. String Insertion, Change Case, etc.) to a batch of files. The interface is also very easy to understand, with all controls divided between three tabs. Perhaps my favorite aspect of Ant Renamer is how quickly it works. Using it, I've been able to rename thousands of files in a fraction of the time it would take other programs. In my line of work (graphic design), Ant Renamer is a vital tool that I find myself using every day.

I didn't imagine that a program like this existed, and it comes in very handy when you have a bunch of files that you've been collecting without order and you need to rename them all, or change part of the title. It also works for PC folders.

This software is available in portable version, it means you can copy the app folder on external device and use it without instal it, and it's less than 3Mo. It can be put on external drive and be used on other computers too. You can make all sorts of differents operations, such as change the extension, enumerations, Single/Multiple String remplacement or use Regular Expressions. You can also add, move or delete character strings to your files. You have choice with other operations like EXIF info or random names attributions. The software can also edit metadata like mp3 tag info and date & time edition. It's really easy to use, 3 differents tabs, on for files, another for action and a third for log. Just drag files inside the first one and switch to the second one to plan what you need. It's possible to batch differents operations in a row and apply it after. The software give you access to a preview on a file selected in the list. Ant Renamer is available in more than 20 differents languages, all around the world. You should find yours.
