If you can't remove a file on Windows, its mostly because of the usage of a too long filename, invalid characters and such.
\nTo solve that there are many tools like unlockers and such which doesn't solve the problem because they doesn't solve the sympthoms:
\nThe filenames.<\/p>\n
So if you step into that kind of problem, open up and commandline and cd to the folder with the \"bad\" file or file.<\/p>\n
And then, do an quick dir \/X<\/strong><\/p>\n That will show up the normal Filename as well as the old \"Dos-Style\" 8 character name. Easy, ain't it?<\/p>\n
\nBy using that short name, you can delete a file with a simple del filename<\/strong> or an folder with an rmdir foldername<\/strong><\/p>\n
