OneDrive with FSlogix in an AVD environment how to prevent profile bloat


We are implementing onedrive to hold known folders (Documents, Pictures, Desktop) and want these files to be "on demand" by default. We have it set via GPO. The main question is, how do I make sure that the files are dehydrated within our 14 day timeframe? We set up storagesense to do it, but how does storagesense have access to unmounted user profiles if storagesense only runs once per day?


Is there an Microsoft supported way of handling Onedrive with FSlogix profiles using storagesense? It appears that as it is now, users could download files over time and they'd never get cleaned up automatically, causing massive storage use as users bring more data in via onedrive.

I see the same problem with our Profiles using AVD. Some of them are over 30GB. Any help would be great. I am manually cleaning them up when they get too large. Not only the manual work, but the cost in Azure is huge since we have to use Premium. We have ~525 profiles. If we could get them under 1TB it would be a cost savings.

Hopefully we can get some more input on this one. Documentation seems light for this kind of configuration.

Who would be the right person to talk to Microsoft about this? I would be glad to open an ticket and update this thread.
@Travis_78 I believe you would need to open it in Azure in your AVD workspace.

I am investigating our bloated profiles, the one I just found shows 56k files in the appdata\local\isolatedstorage - over 20GB.
I have 6 more that are over 26GB to verify.
I am dreading trying to work on this through normal channels. I feel like nobody actually understands the problem but maybe some higher level engineers at MSFT. Was hoping someone would chime in and help.

Hi @Travis_78 this is a known issue, when you or the user delete files, fslogix vhd(x) does not compact itself. Here is a solution for you if you are running the latest fslogix version:

Enable VHD Disk Compaction using the Registry

To enable VHD Disk Compaction using the registry, you'll need to set the following registry value:

  • Key: HKLM\SOFTWARE\FSLogix\Apps
  • Value name: VHDCompactDisk
  • Value type: DWORD
  • Value data: 1

You can do this with PowerShell:

  1. Open an elevated PowerShell prompt and run the following commands:

    Set-ItemProperty -Path "HKLM:\SOFTWARE\FSLogix\Apps" -Name VHDCompactDisk -PropertyType DWORD -Value 1 -Force
  2. Restart the computer.

@hanifaz Yes, but how do you get the files deleted in the first place? Profile compaction is helpful when they finally get the bugs ironed out on the latest FSlogix, but before that, you need storage sense or something that will clear the OneDrive cache store after X amount of time. So far, I don't see that storage sense runs on AVD servers where you can trust it to keep the profile clean. 


Run a test where you push a GPO that has storage sense dehydrate any OneDrive files opened less than a day. Come back after a day and you see that the files are still local to the profile and have not been set back to online only, which is Storage Senses's job.



Try using this Powershell Script in Autostart.

This will activate OneDrive CleanUp for every Connected OneDrive Account or Sharepoint Site.
Data in OneDrive Cache will be flushed every Day.

Thank you for this! I'll give it a shot.
With this script, you say to run the script via the user's login script? Or start menu/startup? Have you used this with success on VHDX / FSlogix users with AVD?


I use this with the menu/startup script. Runs better if you use fslogix Profiles. I had some troubles with GPO Policies in this environment.

At the GPO Logon Script sometimes the fslogix Profile wasn't loaded already and sometimes at logoff is was allready deloaded when the Script runs.


At least, if you deploy it in the Windows Startup Folder, you can use it in any Clone without the need of an GPO. Just create a Link in "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp"


with the following command 


C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -windowstyle hidden -file "C:\Windows\OneDrive-CleanUp.ps1"



and of course don't forgett to put the Powershell Script in the described folder ;)


You can also extend the Script and remove some unwanted Windows Apps for every User like this:

Get-AppxPackage *WindowsAlarms*| Remove-AppxPackage
Get-AppxPackage *windowscommunicationsapps*| Remove-AppxPackage
Get-AppxPackage *officehub*| Remove-AppxPackage
Get-AppxPackage *skype*| Remove-AppxPackage
Get-AppxPackage *xbox*| Remove-AppxPackage
Get-AppxPackage *sol* | Remove-AppxPackage
Get-AppxPackage *real* | Remove-AppxPackage
Get-AppxPackage *weather* | Remove-AppxPackage
Get-AppxPackage *feedback* | Remove-AppxPackage
Get-AppxPackage *zune* | Remove-AppxPackage
Get-AppxPackage *stick* | Remove-AppxPackage
