Created very long folder path - cannot delete (PLEASE read first)

I have read many posts here and elsewhere about related problems, and I have tried some of the solutions, but before I continue, I wanted to post so that I know I"m not wasing my time with unrelated fixes.
______________

IN XP Home, I used cobian backup program to accidentally save "K:\*.*" to "K:\backup - live files\K drive\K\"
(that was a mistake, obviously I meant it to go onto another drive)
It was running all night, so it may have created a VERY LONG CHAIN.

It created a very long chain of subfolders - it let me browse to this point:
K:\backup - live files\K drive\K\backup - live files\K drive\K\backup - live files\K drive\K\backup - live files\K drive\K\backup - live files\K drive\K\backup - live files\K drive\K\backup - live files\K drive\K\backup - live files\K drive\K\backup - live
files\

I renamed (shortened) as many folders as I could access, so now the path is:
K:\xdel\x\x\x\x\K\x\x\x\x\x\x\x\x\x\x\x\x\s\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\K\x\x\x\x\x\K\x\x\K\x\x\x\x\x\K\x\x\x\x\x\x\x\x\x\x\x\x\x\x\K\x\x\x\x\x\x\x\x\x\x\x\x\x\x\K\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\x\backup - live files\

I cannot enter, rename or move the last folder in the chain that I can access.

When I try to delete the folder it says:
Confirim file delete - the folder xdel contains items whose name is too long for the recycle bin. Permanently delete?
I say yes, then it says:
Error deleting file or folder - Cannot delete BACKUP~1: the file name you specified is not valid or too long.



I ran chkdsk /f /r for this but this did not help.

I tried RD /S (aka rmdir /s) but it said "Maximum path length exceeded". (thanks very much)

I tried the fix that uses a script and robocopy:
http://www.windowsitpro.com/article/tips/jsi-tip-9651-how-can-i-delete-a-folder-that-returns-path-too-long-.aspx
but that didn't work - the cmd box loaded about 10 screens of pathh names and then froze (with robocopy at 100% cpu usage)
NOTE - the path may be VERY VERY VERY LONG!

Some ppl say try xcopy too but I dno't see a delete switch. And if robocopy fails, I doubt xcopy would fail.

I tried the java app here:

but that didn't work

And I saw:

I don't want to pay for something if I don't know if it will work.

NOTE - I have seen these two fixes:
~ share the folder, then map a drive and delete from the mapped drive
letter.
~use the subst command to create a virtual drive and delete from Windows explorer all folders underneath

But so many ppl report that this does NOT WORK that I wanted to check here first.
