Setting Isolation Options for Folders and Files
AdminStudio 2025 R2 | 30.0 | Microsoft App-V Assistant
Some settings apply to particular versions of App-V packages. Version-specific differences are noted where appropriate.
The Microsoft App-V Assistant enables you to configure isolation options for folders (in App-V 4.x and 5.x packages) and for files (in App-V 4.x packages). Isolation options indicate how the isolation environment provides access to system resources that the virtual application needs: you can choose to ignore one or more folders on the client system, or you can choose to create a merged view of one or more folders.
To configure isolation options for a folder or file:
- In the Microsoft App-V Assistant, open the Files page.
- Right-click the file or folder that you want to configure and then click Isolation Options. The Options dialog box opens.
- Select the appropriate option.
- Click OK.
Files and folders that have a custom isolation option are marked with a special icon:
