When a VM is new then almost every write to the disk will be to a previously unused sector, so a dynamic drive will appear to grow in size alarmingly. down to the min size needed to hold the guests files, discarding space used by deleted files.īut, as Perry says, there's really no need to be alarmed. And, if host disk space is an issue for you, then look into CloneVDI to compact the host file, i.e.

Just as long as you remember that the guest's opinion of "used space" can only be a guide as to what space the file takes on the host.

What will happen if the vdi file gets to be larger than 100GB in this case? Is the dynamicly allocated storage option the best to use or should I use a set disk size? Is there any way to defrag / optimize the vbox image so its reduced to actual size again?

After a few weeks of using, I'm noticing the vbox file growing, but the space used within the Ubuntu file system is not increasing much. When creating the machine, I chose a 100GB dynamic disk which grows in size as more data is added.
#MAC OS LIST FILES GREATER THAN 1GB 64 BIT#
Hi all - I've installed Ubuntu 64 Bit on a Windows 8 host using VirtualBox and am finding discrepancies between the hard disk space used in the Ubuntu file system vs the Windows or VirtualBox file system.
