Archiving my files after Project Closing

My habit is to archive all my work in hard copy and soft copy after a certain project in utility company finishes. Currently, I put all the hard copy in my living room on a special cabinet full of books and papers resulted from my work. However, the past few days I have thinking to move those papers somewhere in my garage. Why? Because honestly, none of them are used by me. I never touched them in years. I usually browse the soft copy when I need something. And it is easier to find some keywords in soft copy. I do not want to throw it because I use it (even very rare) to teach some new personnel joining the team. It is better to show them in hard copy as I can make some notes and marks directly.

To pursue with the idea of putting them in my garage, I will need a new garage cabinets that can organize my paper so that I can easily index them for future use. I am going to have metal cabinets that can protect my papers against some disasters. Well, just want to be safe. I am not very choosy about the color but a silver color will look nice in my garage to suit the color of the wall.
