I'm using Windows 7 Professional 64-bit, and I somehow managed to create a system of recursive directories. For example, I have directories A, B, and C, which are nested like so: A/B/C. However, when I open directory C, I see directory A. The final directory structure looks something like A/B/C/A/B/C/… If I try deleting this with Windows (both using and bypassing the Recycle Bin) I get an error stating that "The source file name(s) are longer than the system supports." Using RMDIR /s does not work either, as it complains that the folders are not empty (even with the /s parameter specified). How can I delete these directories permanently?
