ITT: tips/discussion on 'other' under storage tab

I know this thing has been troubling a few of us, so i made this thread dedcated to deal with this problem.

If anyone has anything to contriboot you are welcome to teach us more.

As you can see in pic above, I have well over 50 GB long of that yellow light saber- which really ***** considering that I've only got 128 GB of storage, decided to downlaod some games and boost up preformance, i start digging ways to get rid of that thing.

Download a few programmes that people recommended, they are either too advance for a noob like me or i just don't know how to use it.

Turn out I've 10GB+ of iOS apps saved on my computer for some reason-best yet, I've already deleted almost all of them from my phone, so they are just stored on my mac and does nothign but take up sapce.

This is all I've got so far, you can also dumped your words/ ppt into google drive to free up your computer space.
