VC state save

[ebswift]

Thanks for the replies Arno. To summarise this a bit better, I watched the filesystem to see what happens and when rather than relying on my loose observations.

Work is not saved until the VC is closed, and it is not committed to the VC state folder (the one in My Documents under Connectivity Kit) until the VC is re-opened. I've followed the VC state flow now:

The caching location is here:

C:\Users\username\AppData\Roaming\HP_Prime

Testing some conditions:

* Entering some text into a sheets field makes no changes to that folder.

* Closing the VC saves the edits and calc settings to that HP_Prime cache folder.

* Reopening the VC commits the changes into:
My Documents\HP Connectivity Kit\Calculators\VC HP Prime

So, closing the calc nicely *should* bring it back, even if the computer crashes after that (I'm not going to pull the machine power to test that). So, the guaranteed method of not losing work for now is to close the VC and reopen regularly, and have backups going somewhere (I use Google Drive) for "My Documents\HP Connectivity Kit\Calculators\" and "My Documents\HP Connectivity Kit\Backups".
