Whats the best way to store and file paperwork?

I reckon you have 2 options

1) Get yourself some new binders unlike the little ones the big ones are pretty durable and long lasting and they are not expensive.
Binders and a hole punch thats what I got

2) If you willing to splash out get a filing cabinet my dad has one of those takes up a fair bit of space but its easy to find your paperwork.

In folders either sorted by dates and times or topics and then dates and times. Everything I do is stored in different folders for whatever then time sorted

Use a Electronic Document Management System (EDMS).
You can search on the internet for it.
In a EDMS you can store scanned documents and digital documents.

did you work out the solution to your problem

Digitize it.
