Panda Batch File Renamer is a small, easy to use application specially designed to help you rename your files fast.
The intuitive interface provides a flexible way to alter file names quickly. The current and final file names are shown side-by-side on the screen, and any changes are displayed on screen immediately.
Information taken directly from the ID tags of photo and music files can be inserted into the file name. Multiple renaming options can be queued up to make very detailed changes to file names if required.
A history of changes is kept, allowing them to be undone if a mistake is made. Renaming options can be saved so that you do not have to recreate them repeatedly.

Replace block of text, section of text, accented characters, regex
Remove characters, numbers, letters, symbols, all text
