My macbook air says 20GB is in my users folder, but when I open that folder I see only 2GB there. Any idea where this other part of 20GB is? I'm trying to trim for El Capitan.

I don't store anything on the laptop, I only use it for email/ internet.

First up, run Disk Utility and check that there is nothing wrong with the file directory.

If that doesn't work, go to the terminal and type

Code:
du -hd 1 /Users

and see if you can see what is taking up all that space. Note M for Megabytes, G for Gigabytes etc.

Thanks P, the DU went well.
I did terminal, it showed 15 GB of my main user account, no info though.
Bunch of lines for the test user and guest user, all said permission denied, but I don't "think" anything is in those...
In short, the terminal revealed no more than just clicking in finder.

So you move into your main user folder and do it again, like so:

Code:
du -hd 1 ~

to keep digging where the issue is.

Thanks P, found it, hidden library, still don't have habit to remember that is hidden! Culprit is one app, Adobe Bridge, 5gb, I also deleted iphoto, 2GB, never used it in my life. Other stuff too... imap, now that I'm finally with imap for email...
