How To Delete One Million (1,000,000) Files Without Crashing Windows Explorer
Problem:
You have a folder with a large number of files that you need to delete. This is too much for Windows Explorer to handle.
Solution:
FastCopy (it also deletes files fast)

It took several hours but FastCopy was able to delete 948,102 files without slowing down the server at all.
Awesome! Way faster than del *.* when I needed to delete a folder with 7 million files. Thanks!
