HI Ben
First of are you able to see the attribute of the folder it may be read only. to remove the read only attribute do the following.
To view or to remove the Read-only or the System attributes of folders in Windows Vista
loadTOCNode(2, 'workaround');
Click Start, click Run, type cmd, and then press ENTER
To view the syntax for the Attrib command, type attrib \? at the command prompt.
To remove the Read-only attribute and to set the System attribute, use the following command.
attrib -r +s drive:\<path>\<foldername>
Some programs may not operate correctly with folders for which the System attribute and the Read-only attribute are set. Therefore, use the following command to remove these attributes:
attrib -r -s drive:\<path>\<foldername>
If the Run command is not listed on the Start menu
Click Start, click All Programs, click Accessories, and then click Run.
The only other thing I can think of is the folder is corrupt and the file name is to long for Windows to cope with. If so you may need to boot the PC to another type of O/S and delete it that way.
