(How) can I use BackBlaze to synch a few key data files between Windows & Android?

Can I install the BackBlaze client on both Windows and Android, and then synch files, no matter which device updates them?

I am thinking of only a very few key data files, such as my Keepass password data file, a To-Do list, etc.

If so, would I have to move them all to a single directory (and tweak the settings of whichever app uses them to save to/load from that directory)?

Hmm, that sounds like a good idea on the Android side, since the files are primarily created by Windows, and I don’t necessarily want to duplicate that directory structure on Android. Maybe I could use symlinks from Windows, in that common directory, to the real data files?
