Hey all,

Just wondering if setting up a Virtualbox VM with Dynamically Allocated size can overwrite files that already exist on a drive? I've set quite a few up now on an external disk (not the fastest method but storage on my internals is running a little low).

I would assume that it doesn't overwrite existing data, but just wanted to check with you guys to make sure. :)

No. It's just like any other file that gets extended.

Thanks Keith! I was hoping that was the case. Didn't want to overwrite and of my system images on that drive! :D

I've got close to 200GB of VMs on my external data drive and have no problems.

Nope, it can grow to X size that you specified, but only if there is sufficient free space on the hard drive to do so.
