Use Disk Quota in Windows 10
Edited by Jay
If you share a PC with multiple people at work or home, it only makes sense for everyone to have their own account. Let's face it; not everyone uses the PC for the same purpose. That's why it's ideal for users to sign in with their own account to both maintain their preferences, and to have their own space to save their data and files. That said, with several users sharing the same machine, disk space might become an issue at some point. So, as the system administrator, setting specific disk quotas for users is an easy way to ensure your drives never fill up.
Even if you don't share your PC with anyone, setting a disk quota on a drive is a great way leave yourself some wiggle room on your hard disks. When disk quota is enabled, you'll receive a warning when you hit the predetermined volume usage.
There are two options when setting a disk quota:
- Per user - this method allows the system administrator to set a quota for each user account on the PC.
- Per volume - this method sets a quota for an entire drive, no matter how many users sign in and use the PC.
In the following VisiHow guide we used a Sager laptop, running Windows 10 Professional. Don't worry; the disk quota function works the same on Windows 10 Home, as well as older versions of Windows.
**Please note** Since the Anniversary update, disk quotas can no longer be applied to system drives (C:). Also, to use the disk quota feature, your hard drives must be in the NTFS format.
