You can change this value everytime before starting the VirtualBox session.
Hello Werner P. Schulz,

I have 4GB RAM too so I assigned your same amount but still no luck.
I really don't understand this.

Copying stuff via Knoppix works but is very slow and makes my only PC inaccessible for a long time.

I don't know what else to try.
