Is VirtualBox eating up my PC's disk space?

Question

virtual box

I installed VirtualBox, created the main OS on it, about 50 clones were created from it.

Every time I visit them, the memory in which all the clones are stored increases, thereby eating up the memory of my hard drive.

Is it possible to properly delete unnecessary old clone logs so that the last saved information remains?

Clones are needed to store information, when you turn it on and off, the latest data must be saved on the virtual machine.

Answer 1

Run the desired config, delete all snapshots.
Create 1 snapshot for rollback.
The place will be cleaned up.
So the data is already stored on vm ... why take pictures in such an amount
