Error Deleting File or Folder

Had a problem "Cannot delete file: Access is denied" the pathtoolong.com
helped me.

Try unlocker software, it can delete file which is used by other application.

Oh i had the same problem,these files become stacked and are due to long paths,use the tool available at longpathtool.com ,it is a tool which deletes and also searches such undeleteable files and also assists in installation and sharing of long pathed files
