Setting the VFS Path for the Contents of a Predefined Folder in an App-V Package

AdminStudio 2025 R2 | 30.0 | Virtual Package Editor

If a file or folder should exist outside the App-V package’s root folder on the virtual file system, the Virtual Package Editor lets you modify the VFS path for that file or folder.

You may want to specify a VFS path if your virtual application tries to access the files in a folder by referring to a system folder to find the files (for example, looking up the Programs File folder) instead of using a relative path. You may also want to specify a VFS path if end users need to be able to find files when using a file browse dialog box (for example, for templates that are stored in a common file folder).

You can modify a folder’s VFS Path setting by changing its Isolation setting. Using the Isolation setting, you can specify whether you want the selected folder in the App-V package to override the corresponding folder on the client system. The available options are:

  • Override —The App-V application sees only the file content of the folder that is inside the App-V package. For an App-V 5.x package, this setting is inherited by all subfolders. For App-V 4.x packages, selecting this option automatically sets the read-only VFS Path setting.

    note

    Overriding the isolation setting is also referred to as “fully virtualized”.

  • Merge —The App-V application sees a merged view of the file content inside the App-V package and of the file content of the corresponding folder on the physical client system. For App-V 4.x packages, selecting this option automatically clears the VFS Path setting.

To modify the VFS path for the contents of a folder in an App-V package:

  1. In the View List under Application Data, click Files and Folders.
  2. In the Files and Folders explorer, select the predefined folder that contains the files and folders whose VFS path you want to configure.
  3. In the Settings window, set the folder’s Isolation setting to Override. For App-V 4.x packages, the VFS Path setting will then be automatically set.
