Retrieving Directory Sizes and Removing Home Drives

A few days ago I was running into errors and inconsistencies when trying to work with directory size checking. I realized eventually that it was only a permissions issue.

Feel free to use any portion of this script for yourselves to accomplish other tasks, if you don’t have better ways.

My domain just happens to be streamlined nicely to where the file structure for these drives matches their Name property in Active Directory, so this works perfectly for me. (I think I said that correctly?? – Sporadic brain :D)

Here is the updated and working version. I output results to a .txt, nothing fancy just a list that shows me how much space was cleared each time it runs (I set mine to once per week). It should also generate a new report file each time it runs, instead of appending the previous one.

<# .SYNOPSIS Written by: JBear If user account no longer exists in Active Directory, delete Home Drive for associated user. Outputs text file with deleted Home Drives and Total Space Cleared. Purpose of script to to assist SysAdmins with the deletion of End-User home Drives and to mitigate the Human Error factor. Providing the checks and balances to maintain a clean enviroment.
