Increasing size of VMDK files until crash

[makuvux]

(I'm a n00b).

I have 16GB USB stick. I installed here 2 live Linux distros using Virtual box. Which created 2 .VMDK files. In the beginning each file had like 4 - 6 GB. And everything was OK, as I had free 4 GB on USB stick.


But after a while these VMDK files started to increase in their size. Until they filled full capacity of 16GB USB (about 1 week). Now I'm at the point, where these 2 OS doesn't even start through Virtualbox. I just get "Disc full" error.

What did I do wrong? I will format my USB and install these 2 Linux again (I'm not trying to save current files). But I'm afraid, that it will happen again. They will again start increasing in size until they won't even boot.

Why did you select vmdk instead of leaving it to the default vdi?
Anyway 16GB is too small for a single distro OS so two will fill up faster. You can always use fixed disk instead of dynamic so you can lock the OS to a specific size but this too will fail at some point.
