I wish there something like that for RSS feeds. That would be fantastic.

For news specifically, Google News and Ground.news both aggregate and cluster similar news articles.

I like start.me. It isn't something to download but it's a web page. The free service is a great start. I've been using it for years now

I recently found ground.news. it is an interesting news aggregator sight in that it combined multiple sources for each story. It doesn't really answer some of your needs but for each story it shows you which sources are pay-walled and which ones aren't.

At least on the Mac (bsdtar) you can extract single files out of a tar file.

E.g.,

Create the tar file:

tar cvzf pseudo.tgz pseudo/

Move to another directory

cd /tmp/tt

Extract a single file:

tar -xf ../pseudo.tgz pseudo/10481_2017.1069.png

You say PC, so might want to check the tar version you are using and see if there are extra parameters to do the file extraction.
