Reference:https://www.digitalcitizen.life/simple-questions-what-are-disk-quotas-how-set-them-windows/ Explanation: Disk quotas are a way to limit disk usage on a server by setting a maximum amount of space that each user or group can use. Disk quotas can help manage disk space allocation, prevent disk space exhaustion, and enforce fair usage policies. Disk quotas can be set at the volume level or at the folder level, depending on the file system and operating system used.Reference:https://docs.microsoft.com/en-us/windows-server/storage
