@Old-but_Alive: I think there's nothing wrong with indexing ALL stuff relevant to electronics here. One stop shopping. You find it, it's relevant, it doesn't exist here in its current revision, then update, post, etc as long as the links are good. Books, tools, projects, CAD, libraries, IP...why not? Original stuff goes up as a text attachment. There's a ton of stuff on Persian and Chinese sites...heck if most of us can get at it, but there are members here who can bring it over, and should, IMO (those I think should be text attachments as well), ideally rehosted.
However, I agree that "pdf editor this", "Windows X.y", and "MS Word" are readily available and are not needed for one stop shopping within the electronics and development specialty of the membership here. The usual suspects in posting this kind of stuff are newbies who seem to be confused that this is a warez site, which it is not, and posting material that's not here for a reason. Besides, it's better for Sonsivri not to be on the radar of aggressive "Big Software", IMO, and to stay on track of promoting learning, sharing, and actually promoting the purchase of things like tools, books, and papers, when they prove useful or are to be used for commercial development.
