"Other" in Disk Utility The Disk Utility on my Mac shows 100GB of usage by 'Other'. 

I had a look inside ~/Library/Caches, but I did not see anything taking up too much space in there.  

 

I even tried using an app called "Clean my Mac". It didn't do much good. 

 

Here is my question: 
How do I find and delete the files that are taking up nearly 100GB of space and are marked as 'other' in Disk Utility.

I am on El Capitan on a 13 inch 2015 MacBook Pro.
It's probably not just 1 file. Other just means it doesn't fit in any of the other categories.
