#1 Could not remove files

[Thaweesak Taekratok]

I just installed phpnuke to my project. After the
installation, I tried to create table in mysql but it
did not work. So, I decided to delete all the files.
When trying to remove any files from the themes
folder, I got the message that permission denied and
could not remove them. I tried everything but could
not remove it. Do you know how to remove those files
from my project? Right now, I just renamed htdocs
with phpnuke in it to junk and created a new and empty
htdocs folder. If you could remove the junk folder
for me, I will be really appreciated.
