Novell ZENWORKS APPLICATION VIRTUALIZATION 8.0.1 - 8-20-2010 User Manual page 26

Files and folders may optionally be hidden from shell browse dialogs and other applications
enumerating virtual directory contents. This is often used to prevent internal components and data
files from being displayed to the user. To hide a file or folder, click on the checkbox in the
Hidden column next to the desired file or folder.
Note: Enabling the hidden flag only prevents a file or folder from being displayed in browse
dialogs or from directory enumeration APIs. It does not prevent the application, and therefore
potentially the end-user, from accessing the folder or file contents by direct binding.
Flagging files and folders as read-only will prevent the application from modifying the file or
folder contents. To make a file or folder read-only, click on the checkbox in the Read Only
column next to the desired file or folder.
3.11.3 Sandbox Upgradeable Files
By default, ZENworks Application Virtualization allows files in the virtual filesystem to be
upgraded with patches (refer to the topic "Updating a Virtual Application" in the "Registering
virtual applications in the Windows shell" section for more information on application updates).
The Upgradeable flag will allow a specific file or folder to be patched in the sandbox at runtime.
To automatically allow a file or group of files to be upgraded, leave the Upgradeable checkbox in
the column next to the desired file or folder checked.
3.11.4 Filesystem Compression
To reduce executable size, ZENworks Application Virtualization can compress virtual filesystem
contents. This typically reduces virtual application payload size by approximately 50%, but also
prevents profiling and streaming of the app. By default, the Compress Payload option in the
Process Configuration area of the Settings panel is unchecked. This option should remain
unchecked during the build process in order to be able to profile and stream applications.
Note: Disabling payload compression may significantly increase the size of the virtual application
binary.
