Flexible Renamer - batch file renaming
|I downloaded and installed this program
because I need to change the three letter file extension on over 300
files. Within a few minutes I had my files renamed. Easy to install. Easy
to use. Offers the ability to rename MP3's based on the tag information.
Website - Freeware
Quote from the website - a file/folder renaming utility, which can use Wildcard or Regular-Expression and Tag-information (MP3, EXIF).
