Non-video files in a torrent -- innocent?

[Corkson]

I often get a lot of non-video files included in a torrent. I never click to include them in my download, because I'm naturally suspicious when it comes to porn. I know some of them are screenshots, etc, but...

Can anybody tell me why all the "url" and "padding file" stuff is in there?

Are these files anything to be suspicious or wary of?

Am I doing others a service or disservice by only seeding the video files?

I'm including a screenshot of a Transmission window with a few examples. Thanks in advance for any help!

padding file's are from Bitcomet trying to get people switch to them.

url files are saying what sites there are members of.
Do i download them no, would i click on one off the url files no.
