What do you do with warranties, installation materials, etc.?

[Roochita P.]

How do you store all the installation materials that come with everything you buy for your properties? A great example: the allen key that comes with a new sink. Similarly, what about installation guides, warranty information, etc? I'm guessing some of the more seasoned property managers on here might have some tricks of the trade on this. Or, is it just large filing cabinets? Or, do you not store them at all and just assume if something goes bad you'll just replace it? This is for ~20-25 doors. 

I store things in a file cabinet today and although it works, it's a lot of effort for the occasional payoff. Hence, I'm wondering how others do it. Thanks!

I only keep the warranty info and a copy of the receipt in a folder for each unit. All the other junk such as manuals, allen keys, marketing materials, etc goes right into the trash. If I really need them in the future then all the manuals can be found online and all the 'tools' they come with are trash anyways and not worth using twice.
