I have this misunderstanding even if I use Linux a lot that when I work for a long time with a lot of things opened… my RAM fill up and never get down.

I heard it had to do with swap, can you quickly explain why?

Its more likely caching. They just keep the cache of files opened earlier so that its ready for you if you need it immediately again. Also unused ram is wasted ram

Pagecache doesn't count towards used ram.

Also unused ram is wasted ram

Uninstall ram sticks to not waste them.

Yes it won't count used ram. But the other person has a "feeling" that linux uses the same ram even when he quit the apps. So that may count.

Use RAM efficiently. There is no point in freeing all ram

There's no benefit in having RAM sitting idle and empty. Si Linux caches a lot of things.
