Go to the Recycle Bin inside your guest OS and delete all the unnecessary files. Delete unwanted files inside the Windows guest OS. You can do this for both Windows and Linux OS.

Dynamic Size allows for the OS to grow its storage allocation dynamically. If you selected “Dynamic Size” upon creating the VM, then you are set for the next steps. It can’t grow nor shrink beyond a set limit. The reason is because you’ve already agreed to a fixed size for VirtualBox to use for the guest OS. If you selected the “Fixed Size” option when you first created the VM, this guide won’t work for you. If you have a need to free up more storage space, these are the steps to shrink a VirtualBox VM and reclaim lost space. But over time the virtual machine (VM), also known as the guest operating system, may grow due to files you have saved and other activities you’ve done inside the OS.įunnily enough, deleting files directly from inside the VM doesn’t free up the storage space for the host system to use.
