The reality is, you probably don't need half the shit you are saving. What ARE all those papers?
The most important file is "Income Tax".
I do not keep any bills or statements. None. I make a note of the amount due and toss it. I can access anything I need online so I do not keep any of the paper. And I really don't need most of the bills because I can find the amount owed online or I owe the same amount every month. Half of the time the bill or statement goes into the trash unopened.
If you look thru my files you will find several years of income taxes, medical history, ancestry research, original mortgage papers, divorce court order, contracts for major work done on house, car title and original loan papers, vital records, school pictures and report cards (sentimental value), and vet records. That is about it. I add stuff to one of the files every few months at the most.
