DOS batch file to recursively find the size of each directory

[b***@lycos.com]

Greetings,

http://www.bish.co.uk/forum/index.php?topic=58.0 provides some scripts to find the size of each filesystem subtree rooted at a directory. These scripts have the limitation that the loop never quits and to exit the batch file you need to use Ctrl-C and then type ECHO ON to get your DOS prompt back. I have modified the script to get past this limitation. Here's my code. Enjoy.

Thanks,
Bhat
