How to Set Disk Quota Limit and Warning Level in Windows 10

If you have more than one user account then each user gets their separate account but the amount of data which they can store doesn’t have any limitation, in such case the chances of users running out of storage are very high. Hence, Disk Quotas can be enabled where the administrator can easily allocate the amount of space each user can use on a specific NTFS Volume.

How to Set Disk Quota Limit and Warning Level in Windows 10

With Disk Quota enabled, you can avoid the possibility of one single user can filling up the hard drive without leaving any space for other users on the PC. The benefit of Disk Quota is that if any single user has already used their quota then the administrator can allocate some additional space on the drive to that particular user from another user who might not be using the additional space in their quota.

Administrators can also generate reports, and use the event monitor to track the quota uses & issues. Additionally, administrators can configure the system to log an event whenever the users are near their quota. Anyway, without wasting any time let’s see How to Set Disk Quota Limit and Warning Level in Windows 10 with the help of the below-listed tutorial.
