Defining Isolation Modes for the Physical File System

Isolation modes determine the level of read and write access to the native file system outside of the virtual environment. You might adjust isolation mode settings depending on the application and the requirements to protect the physical system from changes.

The selection of isolation modes in the capture process determines the value of the DirectoryIsolationMode parameter in the Package.ini file. This parameter controls the default isolation mode for the files created by the virtual application except when you specify a different isolation mode in the ##Attributes.ini file for an individual directory.

The selection of a directory isolation mode does not affect the following areas:

• Omnissa ThinApp treats write operations to network drives according to the SandboxNetworkDrives parameter in the Package.ini file. This parameter has a default value that directs write operations to the physical drive. ThinApp treats write operations to removable disks according to the SandboxRemovableDisk parameter in the Package.ini file. This parameter has a default value that directs write operations to the physical drive.
• If you save documents to the desktop or My Documents folder, ThinApp saves the documents to the physical system. ThinApp sets the isolation mode in the ##Attributes.ini files in %Personal% and %Desktop% to Merged even when you select WriteCopy isolation mode.
