Updated Recursive Filetree for Vista x64

[LurkinDerk]

Thanks to Stefan Pendl.
This is a modification to his recursive filetree program which went into a loop on my Vista x64. The modifications changed a few things to allow the recursive filetree program to complete. I added a subdirectory stack instead of Stefan's ever-expanding strings. I also allowed the program to bypass certain Windows systems folders. The original program encountered a runtime error because of some corrupted data files on my disk. I added the ON ERROR stmt to bypass the Files command when it failed because of some error. The program runs quickly in 8 seconds on my Vista x64 with a highly loaded file structure (many highly nested subfolders). I hope this version may be useful to someone.
