is quickpar a hash creating prog?

btw - this soooo should be stickied!

It uses Reed-Solomon error correction. You can read up on it here:

NOTE: You cannot use quickpar except for integrity checks for very large files (10's of GB). For those I will use winrar to break them into 700mb volumes and create parity data for 10 at a time. You can get 20% coverage that way. If you break them into groups of 5 you can get 45% coverage. If you are really paranoid you can get 100% coverage by narrowing it down further. Whatever works for you.
