Renaming playlist in director

[citizencoolville]

I want to rename the playlist in the directory.

example:

>I rename playlist plf26D.m3u8 to TEST1
>Winamp recreates plf26D when I rename it
>Now I have both plf26D and TEST1 in the directory
>Winamp only uses plf26D

How do i fix this?

I just want the names inside winamp to correlate to the directory, thus making sharing between PCs easier.
