have you tried renaming the folder to something else, then delete it? I had some problems with files I downloaded with insanly strange names. To fix/remove them, they had to be renamed through dos as windows would crash when trying it. Might be worth trying, that is if you have not already.
Something else is a script I created for doing this... link to come...
This is for removing a file. This is a folder, right? ... so if you want, I can do one for removing the directory. Just let me know...
Perl has a nice little module for removing dirs.
$path = "C:\\Documents and settings\\roy\\desktop\\new folder\\music\\misc\\2pac\\";
@folders = qx(dir $path /a:d /b /s);
install the perl program listed in the post link above.
Then copy the code above to a text file and save it as Dir_Scan.pl
open a cmd window, click and drag the Dir_Scan.pl file into it and then press enter while in the window. This should incremenet the folders on screen. Post the screen shot.
