After upgrading your computer OS like upgrading Windows 7 to Windows 10 or partitioning a hard drive, there is a chance that you may find a Z drive in File Explorer which is only hundreds of MB. Then, you decide to access it to see what there is. However, when you double-click on it, a window pops up “You don’t currently have permission to access this folder”. So, you run Disk Management to check the Z drive’s details and tried deleting it from there. However, this drive doesn’t even appear in Disk Management.
What is this Windows 10 Z drive? Actually, this drive contains some system restore files and temporary files which are not harmful and give you the option of restoring back to your previous versions of Windows. And because this drive only takes up a little space, basically hundreds of MB at most, it’s usually recommended to leave it there.
Although it’s unnecessary to remove the system Z drive Windows 10, still, if you insist on removing it from your PC anyway, you can choose from the following 5 methods to get it done.
