Crocodile Mod

I'm a fairly poor person so I don't have the money to buy the Steam versions of AoE2, nor the expansion packs such as African Kingdoms. I downloaded the files for a crocodile mod (http://aok.heavengames.com/blacksmith/showfile.php?fileid=11867) but my computer can't open .drs files, even when I download a software specifically for it.

I know this sounds incredibly lazy but can someone please edit the linked crocodile mod into the appropriate files and then send the edited files to me? I'd prefer the crocodile to replace the Rabid Wolf or Dire Wolf graphics, or the wolf as a whole. Thanks in advance.
