What helps you stay organized when dealing with different types of contracts?

When I first started renting and working at the same time, I was shocked by how quickly documents started piling up. Between my job contract, rental agreement, and even small service contracts like internet and insurance, it felt like everything needed my attention at once. One time I misplaced a paper and had to spend hours tracking it down, which made me realize I didn’t have a proper system. Since then, I’ve been trying to figure out the best way to keep contracts safe and easy to find, but I’m still not sure what works best. Do people here rely more on digital storage, or do you prefer having a physical folder for everything?
