Portmaster Archives

I know that many Portmaster games are paid and that's okay.

Suppose I'm trying to install a game, and I need to get the files from my folder in that game's directory on Steam.

But at the moment I don't have access to my personal PC, because maybe I'm working away, or something like that and I decide to download them from the internet.

Is there somewhere that someone happened to have archived these necessary files?
