Long File Names In Vista Nothing Works

I'm running Vista Ultimate 32bit, and on one particular drive, I had backed up some files with extremely long names from a different system. The kind of stuff you find as temp files in the "Content.IE5" sub directory of "Temporary Internet Files."

Now, I'm trying to delete a parent directory where all these files are located. But Vista, in it's ultimate wisdom is giving me an error, indicating that it cannot delete these files becuse the overall path is too long - It suggested I move the files to a place with a "shorter path," but when I try, it won't let me do it for the same damned reason! The Source path is too long Nothing works.

Attempting to delete individual files, the parent directory, the "grand parent" directory all fail because Vista attempts to calculate/sum space and thus accesses each individual file, and fails because the "path is too long." When I try to rename individual files, it grays out the "rename" option. Is there any way I can either get rid of these files or bypass the "file length" warning so I can delete them? Formatting the drive is *not* an option. This is a SAN drive with lots of stuff on it and I'd never be able to off load it all.
