Stumble it!If you want industrial strength file renaming there are several great choices: First there’s Lupas Rename 2000 [1]. This is a small utility for Win 98 and later that globally renames all the files in a directory and its subdirectories. It can convert names to upper/lower case, change the case of the first letter, add text, left crop, right crop and just about anything else you can think of. And unlike DOS based utilities, it will work on hidden files as well. Add in a nice GUI interface, an undo feature, full preview of changes, MP3 tag renaming, support for regular expressions and the fact that it’s free and you have an outstanding product.
The second and equally attractive option is Flexible Renamer [2]. It’s quite similar to Lupas and choosing between them is not easy. Lupas seems to me to be easier to use for simply renaming files while Flexible Renamer has the edge with MP3 tags. Flexible Renamer can also can bulk change file attributes while Lupas can’t. It also runs without installation, a definite plus.
