You can drop the downloaded .exe file in any part of the disk or a USB flash drive and just click it to launch the application. It does not need any DLLs, modify Windows registry settings, or create extra files on the disk without your permission. To remove it, you can simply delete the .exe.

It's packed in an intuitive interface made from a single window divided into three parts for carrying out tasks, similar to a wizard UI. You can get started by selecting the files you wish you work on, as well as by changing their order in the task list.

In the second stage, you can specify a base name to be shared by all files, choose the numbering style (one or two digits with starting zero, or with leading and starting zero), and pick the preferred separator (space, hyphen, underscore, spaced hyphen, underscore, or no separator).

Before proceeding with the renaming job, it's possible to preview the new names and go back to make any necessary adjustments. Batch File Renamer can be instructed to replace the original files or to make new copies. The second option is advisable as a backup measure.

Moreover, you can review all notes before triggering the task when it comes to the number of files, new name pattern, output folder, and alert (e.g. original files will be deleted).
