OK, I wasn't aware that the shown 2GB size was due to the limitation of BoxCryptor.
So it was basically a coincidence since the free Dropbox version also has a 2GB limit.
Anyhow, would it be hard to implement a customizable BoxCryptor drive capacity limit like in my previous post? I think it would make sense, since other cloud storage providers also have a set capacity limit.
If the user would be given control over this parameter, one would always see, how much space there is actually free in one's cloud storage!
Best regards!
