You can specify certain locations of Writable Volumes to exclude them from persisting across sessions or getting overwritten.
- If the user modifies the locations that are excluded, the changes are lost when the user logs off the machine.
- You must know what application behavior and data will get stored in the folders you want to exclude.
- Do not use generic locations such as \REGISTRY\MACHINE\SOFTWARE or \Program Files(x86)\. Using generic locations can cause all application updates to be erased.
- You can include paths within the users profile directories so that specific applications or files can be excluded from being captured.
- If the Writable Volume is UIA-only, all user profile paths are excluded and you do not have to explicitly specify any user profile paths for exclusion.
- User profile exclusions are not supported with computer-based Writable Volumes which are attached during computer startup.
- You must have administrator privileges on the machine where the App Volumes agent is installed.
- You must have uploaded the policy file (snapvol.cfg) and scripts to the Writable Volumes.
To upload the files to a Writable Volume, see Update Writable Volumes.
For an understanding of (default and custom) policy files and scripts, see Policy Files and Scripts.
- Log in as administrator to the machine where the App Volumes agent is installed.
- Locate and open the writable volumes configuration file, snapvol.cfg.
- Add the following entry in the snapvol.cfg file, where path is the location of the application or registry that you want to exclude:
exclude_uwv_file=path.You can specify multiple exclusions.
Example: Exclude an Application Location
The following examples exclude the folder and registry location of Notepad++ from being overwritten during an update:
exclude_uwv_file=\Program Files (x86)\Notepad++
What to do next
You must test the application after applying any Writable Volumes exclusions to ensure that the application works as desired.
