Disk Space

Post by jameshoty »

Hi

I have a Windows 7 running and yesterday I received warning that it is running out of space. What should I do to allocate more space?

Depends on where the warning comes from. It can come from 3 places:

Inside the Windows 7 OS: You are running out of disk space inside the guest. Same thing can happen in a real PC. Fill up a drive, physical or virtual, and you're out of space. Remove unnecessary files inside the guest OS or make the guest drive bigger.

In the host PC: Your host OS is running out of disk space. Same applies as in the guest OS above: Remove unnecessary files inside the host OS or transfer everything to a bigger host drive.

From Virtualbox: If your guest drive is dynamic (most guest drives are) then it could get bigger than the free space left on the host drive. For example, let's pretend you made a 120GB dynamic drive for your Windows 7 guest. It starts off really small and gets bigger the more data you store in the Windows 7 guest Perhaps after installation of 7 and some other programs it gets to 40GB size, but can increase up to the full 120GB. Meanwhile you fill up the host drive with other stuff, and you now have only 50GB free space. The Windows 7 drive has 80 more GB it can increase but the host drive only has 50GB free. Eventually the Windows 7 drive will want to get bigger than the free space on the host drive. Remove unnecessary files inside the host OS or transfer everything to a bigger host drive. Or remove unnecessary files in the Windows 7 guest then shrink the guest drive.

Let us know where the warning message actually showed up and we can give more guidance.
