Differences between Ubuntu VDI, VHDX, and VirtualBox Files: Safely Deleting the Canonical Group Limited Folder

When using Ubuntu on a VirtualBox virtual machine with a Windows 10 host, you may notice two large files: a VDI file and a VHDX file, as well as a folder named "Canonical Group Limited". This article will explain the differences between these files and how to safely delete the "Canonical Group Limited" folder.

VirtualBox Disk Image (VDI) Files

VDI files are the default disk image format used by VirtualBox. They are used to store the virtual hard drive of a virtual machine. VDI files are specific to VirtualBox and cannot be used by other virtualization software.

Virtual Hard Disk (VHDX) Files

VHDX files are a disk image format used by Microsoft's Hyper-V virtualization software. They can also be used by VirtualBox, but they are not the default format. VHDX files offer several advantages over VDI files, such as larger maximum disk size, support for larger sector sizes, and improved performance.

Canonical Group Limited Folder

The "Canonical Group Limited" folder is a folder that is automatically created by VirtualBox when you install a Ubuntu virtual machine. It is used to store virtual machine configuration files and other data. The folder is named after Canonical, the company that develops Ubuntu.

Safely Deleting the Canonical Group Limited Folder

If you no longer need a Ubuntu virtual machine, you can safely delete the "Canonical Group Limited" folder. However, you should first make sure that the virtual machine is no longer running and that the VDI and VHDX files are no longer in use. To do this, follow these steps:

1. Shut down the Ubuntu virtual machine.
2. Close the VirtualBox application.
3. Delete the VDI and VHDX files associated with the virtual machine.
4. Delete the "Canonical Group Limited" folder.

It is important to note that deleting the VDI and VHDX files will permanently erase all data stored on the virtual hard drive. Therefore, you should make sure to back up any important data before deleting these files.
