I believe that it's only FAT that is limited to 255 characters but many programs may have that limit too.

If you want to rename or move the file here's a trick I came across a few months ago:

At a command prompt enter something like:

subst x: d:\_MP3\CLASSICAL

You should then be able to access the file successfully through X: to do what you need to with it because the resulting path names will be less than 255 characters long.

You may also find that you can just move the file from the command line if you're sat in the directory.
