is there a way to do a checksum? from my understanding a checksum is a better way of identifying the integrity of a file. to prevent fradulant attempts where people could just rename of the file and even have the filesize close enough, id like to perform a checksum on a particular file before contuning with the rest of the script this link mentioned here is down.. and couldnt find any other posts on it http://www.autoitscript.com/forum/index.ph...amp;hl=checksum
