Linking to File Types .zip .pdf .exe - Adds Weight to Pages?

Thread Title:
Variety of File Formats
Thread Description:

SEOChat memeber Jasontnyc talks about the possiblilty of linking from a page to various file formats like .zip and .exe giving extra weight to them for ranking.

The reasons I think the theory is valid:
A variety of file types usually means a site with lots of information such as user guides, service info, etc which could be seen as a benefit
Sites with .zip links probably are offering software downloads which could be seen as a benefit
etc, etc

Until it's tested, that's exactly what it looks like of course, pure speculation but it is an interesting theory is it not?

The thread itself is interesting as a whole too, check it out... [ Warning ] Dodgy Avatar Alert!
