Can't delete folder. Infinitely looped folders created within each other
Solution 1:
Boot up some linux live distribution and delete it from there.
Solution 2:
You might try using the SUBST to map a long path to a new drive letter. That may get the path down short enough for you to delete some of the lower directories first.
Solution 3:
Try the command line:
rmdir /s /q "C:\path\to\folder"
