eMule / eDonkey Corrupted Files?

[BooYaKaSha113]

I've been wondering this since I tried downloading a certain ISO file from eMule where all the exe files were corrupted. I need some expert info on this:

What if someone donwloaded a fully working ISO file from eMule/ eDonkey, then purposely corrupted parts of it so its contents no longer worked, yet the names and file size of the file were exactly the same, then uploaded it to everyone else. Would emule / edonkey recongnize this as being the same file as the working ones? Or does it use more sophisticated means of identifying which files are identical from different users?

If this is possible, what's to stop someone who doesn't want a certain popular file shared on the network for whatever reason from doing this, then sharing only that one file so it quickly mixes itself with all the working files and corrupting all future downloads? You can't pick and choose which users you want to download from, can you?

Just a thought. Someone put my mind at ease.

the hashing process makes different hashes for files even that have the same size/name.

if someone purposely corrupted a file, another person would have to have that file to have a multisource download.

i usually download the one with the most sources to prevent getting bad files, and it usually works.

Thanks for the info.

This is the only file I've had problems with so far. It's also the only version of that file on there. Oh well.
