Looking for the source of my lack of hard drive space

[LC1331]

I hadn't went into my file explorer in about a week, and when I did, my SSD reported only having 1gb of 115 free. The week before, I had 25gb free. I am having trouble finding the source of the lack of space. Is there any way I can order folders in order of size? Or find the source? Really annoying.

I would do a disk cleanup but use this program http://www.uderzo.it/main_products/space_sniffer/ it will tell you in detail where and how much is stored
