PowerTip: Use PowerShell to Find Size of User Profile
Summary: Use Windows PowerShell to find the size of your user profile.
Use the Get-ChildItem cmdlet, recurse through your profile directory, pipe the results to
the Measure-Object cmdlet, select the Length property, and add Sum and Maximum.
This command measures the ED directory, and dir is an alias for Get-ChildItem:
PS C:\Users> dir .\ed -Recurse | Measure-Object -Property length -Sum -Maximum
