Check if the fiels are marked as read only. You cannot delete directly such  files from DOS

It may be a simpler problem that sirbounty's solution...

Open up the command prompt, go to the directory where you want to delete the files and try typing

attrib <filespec>

where <filespec> is the file spec of the files that you were trying to delete (ie, "*.jpg").

This will list the file attributes of the offending files. If the files were copied from a CD then MS (for some silly reason that's nobody has managed to explain) decided that they should all copied over as read-only onto your hard disk.

If the files are listed as read only, type the following into the command prompt:

attrib -r <filsepec>

You should then be able to delete the files in DOS.
