Brename

Brename is a command-line application that enables you to rename multiple files at the same time using automatic numerical incrementation.

This way, you can organize your data in no time, such as photo, music or movie collection. It's geared toward advanced users who are already familiarized with console tools.

The usage is brename filename new_filename mask, where you can specify the name of one or more files you want to change (including wildcards), while keeping in mind that files with system, hidden and read-only set attributes are automatically ignored.

The mask is the starting position of the counter and the default one is 001, but it can be modified to suit your preferences. For instance, you can rename all files from a specified directory with the JPG and JPEG format.

If tasks are not carried out properly, the tool reveals exit codes which tell you the nature of the issue: incorrect number of parameters ("1"), cannot find or rename the specified file ("2"), or allocation error ("4"). If there are no errors, it returns "0".

The entire program's packed in a single executable file that can be saved in a custom directory on the disk or copied to a removable storage unit, in order to directly run it on an computer with minimum effort and no previous setup. It doesn't make any changes to your system registry or create files on the disk without your permission. If you want to uninstall it, you can simply delete the .exe.

We haven't experienced any stability issues in our tests, thanks to the fact that the utility didn't freeze, crash or prompt error messages. It left a small footprint on system resources usage, running on low CPU and RAM. You can test Brename for yourself, since it's freeware.
