Something that other apps have on you at this point is a central storage cache.  MS Intune comes with 20gb storage for software you may need.  Like for printer drivers or apps commonly used by users.  Don't worry not going over to MS Intune.  Maybe build your file management feature with this in mind.  Just another idea and something I'm struggling with at the moment, currently using scripts and stuff.

 

You could even sell it as an addon to your current saas.
