About software virtualization
When a virtual application creates or modifies application data, the data files can
be saved in the application layer. If the layer is reset, the files are lost. An exclude
entry excludes files from a layer and saves them in the base file system instead.
An exclude entry can exclude a file type or a directory. If an exclude entry excludes
a directory, it can also exclude its subdirectories.
Exclude extries can be created with the following products:
Any WiseScript product such as WiseScript Editor or WiseScript Package
Editor. The Set SVS Exclude Entry script action can create exclude entries on
client computers.
Software Virtualization Solution or its new version, which is called Symantec
Workspace Virtualization.
For more information about exclude entries, see the respective product s
documentation.
Types of exclude entries
Table 16-1
Type
Layer exclude entry
Global exclude entry
A data layer takes precedence over an exclude entry. If a data layer contains the
same data that an exclude entry excludes, the data is saved in the data layer.
See "About data layers"
Description
Redirects the files from a specific layer to the base file
system.
For example, a virtual software layer for Microsoft Word
can have a layer exclude for the following file types: DOC,
RTF, TXT. When Word saves a file with any of these file
types, the file is saved in the base file system and not in the
layer.
Note:
When you use Managed Software Delivery to
virtualize software during installation, the resulting layer
has no layer exclude entries.
See "Virtualizing software during installation"
Redirects the files for every virtual software layer on a
computer to the base file system. For example, a computer
can have a global exclude for PDF files. If a layer creates
PDF files, the files are excluded from the layer and saved in
the base file system.
By default, when the Software Virtualization agent is
installed on a managed computer, global excludes are
created for the My Documents and the Desktop directories.
