of course!
* goto "Start", "Run" (if you don't see run press the Windows Key + R)
* Type in "cmd" en press "ok". a command prompt will open.
* Goto the drive where the undeletable folder resides for example D:
* So you will have type in D: <enter>
goto the folder where the problem folder is located, in my case it was located in
D:\_cache\delete\
the folder i could not delete was called "happy tree friends" (d:\_cache\delete\happy tree friend) so i typed:
D:<enter>
cd _cache<enter>
cd delete<enter> (As you can see I don't open the problem folder itself)
* type: dir /x<enter>. A directory listing will appear containing the 8.3 names of the folders and files, in my case it showed: happyt~1
* then type: rd happyt~1<enter> (replace happyt~1 with the folder name you see)
The folder will be deleted.
Good luck. I hope it makes any sense, if you have any other questions just shoot!
NOTE:
rd = remove directory/folder
cd = change directory/folder
