Flash file system disk space

Firmware Device OS

I'm replacing my Argon with Photon 2 and want to use the flash file system. I got it working right away and the few basic tests I ran worked flawlessly.

However, I could not find any way to determine how much disk space is used or is free. I guess I can add up the file sizes and do some calculations based on block size but I'm waaaaaay too lazy for that exercise. Any suggestions?

Thanks!

I don't believe there is an easy way to do this.
File system | Reference | Particle covers the file system in more details.

I'll have to defer to @rickkas7, but they are out until next week.
