Adding a Disk Quota Entry

Creates a custom disk quota entry for a user named jsmith. This script must be run on the local computer.

Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
set objUser = colDiskQuotas.AddUser("jsmith")
set objUser = colDiskQuotas.FindUser("jsmith")
objUser.QuotaLimit = 50000000

Configuring Disk Quota Settings

Changes the warning threshold and default quota limits for drive C.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colQuotaSettings = objWMIService.ExecQuery _
    ("Select * from Win32_QuotaSetting")
For each objQuotaSetting in colQuotaSettings
    objQuotaSetting.DefaultLimit = 10000000
    objQuotaSetting.DefaultWarningLimit = 9000000
    objQuotaSetting.Put_
Next

Deleting a Disk Quota Entry

Deletes the disk quota entry for a user named jsmith. This script must be run on the local computer.

Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
set objUser = colDiskQuotas.FindUser("jsmith")
colDiskQuotas.DeleteUser(objUser)

Enabling Disk Quotas

Turns on disk quotas for drive C.

Const ENFORCE_QUOTAS = 1
StrComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDisks = objWMIService.ExecQuery _
    ("Select * from Win32_QuotaSetting Where VolumePath = 'C:\\'")
For Each objDisk in colDisks
    objDisk.State = ENFORCE_QUOTAS
    objDisk.Put_
Next

Enabling Disk Quotas on the Local Computer

Enables disk quotas for drive C on the local computer. Requires Windows 2000 or later, and cannot be run against a remote computer (unless you use the WSHController object). To enable disk quotas for a different drive, change C:\ in line two to the appropriate drive letter (for example, D:\). To disable disk quotas, set the value of the constant ENABLE_QUOTAS to 0. To enable, but not enforce, disk quotas, set this value to 1.

Const ENABLE_QUOTAS = 2
Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
colDiskQuotas.QuotaState = ENABLE_QUOTAS

Enumerating Disk Quotas

Enumerates disk quota information (including user name, warning and quota limits, and disk space used) for each disk quota entry on a computer.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDiskQuotas = objWMIService.ExecQuery _
   ("Select * from Win32_DiskQuota")
For each objQuota in colDiskQuotas
    Wscript.Echo "Disk Space Used: " & vbTab &  objQuota.DiskSpaceUsed
    Wscript.Echo "Limit: " & vbTab &  objQuota.Limit   
    Wscript.Echo "Quota Volume: " & vbTab &  objQuota.QuotaVolume     
    Wscript.Echo "Status: " & vbTab &  objQuota.Status 
    Wscript.Echo "User: " & vbTab &  objQuota.User     
    Wscript.Echo "Warning Limit: " & vbTab &  objQuota.WarningLimit
Next

Enumerating Disk Quota Settings

Enumerates the disk quota settings for each drive on a computer.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colQuotaSettings = objWMIService.ExecQuery _
    ("Select * from Win32_QuotaSetting")
For each objQuotaSetting in colQuotaSettings
    Wscript.Echo "DefaultLimit: " & vbTab &  objQuotaSetting.DefaultLimit
    Wscript.Echo "DefaultWarningLimit: " & vbTab &  _
        objQuotaSetting.DefaultWarningLimit    
    Wscript.Echo "ExceededNotification: " & vbTab &  _
        objQuotaSetting.ExceededNotification   
    Wscript.Echo "State: " & vbTab &  objQuotaSetting.State    
    Wscript.Echo "VolumePath: " & vbTab &  objQuotaSetting.VolumePath
    Wscript.Echo "WarningExceededNotification: " & vbTab &  _
        objQuotaSetting.WarningExceededNotification    
Next

Enumerating Disk Quota Settings on the Local Computer

Enumerates the disk quota settings for drive C on the local computer. Requires Windows 2000 or later, and cannot be run against a remote computer (unless you use the WSHController object). To enumerate disk quota settings for a different drive, change C:\ in line two to the appropriate drive letter (for example, D:\).

Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
 
If colDiskQuotas.QuotaState = 2 Then
    Wscript.Echo "Quota state: Enabled and enforced"
ElseIf colDiskQuotas.QuotaState = 1 Then
    Wscript.Echo "Quota state: Enabled but not enforced"
Else
    Wscript.Echo "Quota state: Disabled"
End If



Wscript.Echo "Default quota limit: " & colDiskQuotas.DefaultQuotaLimit
Wscript.Echo "Default warning limit: " & _
    colDiskQuotas.DefaultQuotaThreshold
Wscript.Echo "Record quota violations in event log: " & _
    colDiskQuotas.LogQuotaLimit
Wscript.Echo "Record warnings in event log: " & _
    colDiskQuotas.LogQuotaThreshold

Enumerating Disk Quotas on the Local Computer

Enumerates the disk quota entries for drive C on the local computer. Requires Windows 2000 or later, and cannot be run against a remote computer (unless you use the WSHController object). To enumerate disk quota entries for a different drive, change C:\ in line two to the appropriate drive letter (for example, D:\).

Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
 
For Each objUser in colDiskQuotas
    Wscript.Echo "Logon name: " & objUser.LogonName
    Wscript.Echo "Quota limit: " & objUser.QuotaLimit
    Wscript.Echo "Quota threshold: " & objUser.QuotaThreshold
    Wscript.Echo "Quota used: " & objUser.QuotaUsed
Next

Enumerating Disk Space by User Using Disk Quotas

Uses disk quotas to report the amount of disk space being used by each individual user on a computer.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colQuotas = objWMIService.ExecQuery _
    ("Select * from Win32_DiskQuota")
For each objQuota in colQuotas
    Wscript.Echo "Volume: "& vbTab &  objQuota.QuotaVolume
    Wscript.Echo "User: "& vbTab &  objQuota.User      
    Wscript.Echo "Disk Space Used: "& vbTab &  objQuota.DiskSpaceUsed
Next

Modifying a Disk Quota Entry

Modifies the disk quota warning threshold and disk space limit for a user named jsmith. This script must be run on the local computer.

Set colDiskQuotas = CreateObject("Microsoft.DiskQuota.1")
colDiskQuotas.Initialize "C:\", True
set objUser = colDiskQuotas.FindUser("jsmith")
objUser.QuotaThreshold = 90000000
objUser.QuotaLimit = 100000000
