How does Windows work out the 4 digit hashes in file names like this:

AEFA0~1 (" a")
AB748~1.B (" a.b")
AB3445~1 (" ab")

Is it just a random number?

Is this too much voodoo?

Nope!

(Note: the hash is only found in NT-based OS's)

Thanks. This was clever detective work. I like the way he created 10 million files to test the Windows routine.
