How to find the source of some software

Hi guys,

funny question but maybe someone can help.

I use some I guess you could call it 'specialist software' I have found a pretty reliable source for this software, but its on a chinese forum, and they have a stupid credit system to be able to download it off plus understanding it is difficult. Anyways there is one guy who has all the latest updates pretty quickly, but the funny thing is, this guy is Chinese, yet all the software is in English, so I know he is not the creator of the software, but must find it else where and upload it, he wont tell me his source because he gets benefits from this credit system.

So if there a way, having a exe file, or dll file etc to be able to google some string from that to find all the hits on google. My guess is there is some other forum he is finding this off. I would love to go straight to the source

For example, with torrents there is unique hash string I can google and find all the places its uploaded, is there anything I could do with program files to do the same?
