Flash Renamer is a powerful file renaming tool that allows you to change file names for dozens, hundreds or even thousands of files at once. It offers various ways of renaming the files, including uppercase, lowercase, prefixes, string replacements, sequential renaming and more. It includes special support for MP3 files, allowing you to rename the files based on their ID3 tag information (e.g artist name, album etc.). Flash Renamer also provides a handy thumbnail browser that allows you to view small images of photos, which makes it perfect for digital camera owners that wish to rename and organize their photo collection. The real-time preview instantly shows you what the new file names will look like, and if you make any mistakes, you can use the Undo feature to reverse the changes.
