Details

This article provides steps on how to allow end users to see the size of writable volumes.

Solution

You can view the space remaining in writable volumes from the App Volumes Manager.

You can also allow the end user to see available space on their writable volume, from their system volume. After an appropriate, create a new registry key during the App Volumes Agent configuration:

Navigate to HKLM\System\CurrentControlSet\Services\svdriver.

From this location, create a new registry key called Parameters.

Within the Parameters key, create a new key called ReportSystemFreeSpace with a DWORD value of 0 (zero).

OR

Alternatively, you can run a command from an elevated CMD prompt to create the correct key and value:

reg add hklm\system\currentcontrolset\services\svdriver\parameters /v ReportSystemFreeSpace /t REG_DWORD /d 0

After you make the registry modifications, and reboot the system, the C:\ object now reports free space on the user’s writable volume of the total C:\ (which is 9.41 GB total in this case).

Note: Total space still reflects the C:\ value.

Setting the ReportSystemFreeSpace to 0 shows the value of the writable volume when the space is smaller than the C:\

In order to display free disk space of the writable volume only, set the "ReportSystemFreeSpace" key to a value of 2.

Setting the ReportSystemFreeSpace to 1 shows the free size of system C:\

Setting the ReportSystemFreeSpace to 2 shows the free size of the writable volume.

If the free size of the writable volume is smaller than the free size of system C, setting ReportSystemFreeSpace to 0 or 2 will show the same value which is the free size of the users writable volume.

Related Information

By default, two writable volume templates are available when App Volumes Manager is installed:

UIA Only – User-installed applications only

UIA and User Profile

The UIA Only writable volume template is intended to capture user-installed applications. It is for use when you are combining App Volumes with a user-profile solution, such as VMware User Environment Manager, or a third-party user-profile solution. This template does not capture the user-profile data.

The UIA and User Profile writable volume template is intended to capture user-installed applications and the local profile data of the assigned user.

If a user’s writable volume has reached or is about to reach full capacity, it can be expanded.
