Where Prezi Classic Desktop stores its data

I have just bought a new PD with a 128Gb C: drive and a 1Tb D: drive.
When Prezi desktop synced, it filled up the whole C: and jammed the whole computer.
I’ve done a temporary fix by moving the whole Prezi folder onto D:
But can I set it so that D: is the default storage location for the Prezi files?

Many thanks
