windows 7 - Something is eating my SSD space

I noticed that my 120GB SSD is almost full, but I have only 55GB data on it.

I ran Disk Analyzer and listed folders and files have around 55GB of data, and yet it says that I have only 4.4GB free memory. Also, every time I delete some data to clear some space, after few days it's almost full again even though I didn't download anything new.

I have checked the paging file and it's about 8GB (included in those 55GB from the beginning), and hibernation is disabled.
