+SIS Files</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>An embedded SIS file is a file that is placed in another SIS file. Embedded
+SIS files are useful for packaging multiple components into a single SIS file.
+These components can be removed independent of one another. For example, if
+a SIS file needs to install an application and a library that is shared with
+other installed applications, the shared library can be installed as an embedded
+SIS file, so that when the application is uninstalled, the shared library
+remains on the Symbian device if required. </p>
+<p>Embedded SIS files are installed and removed along with the file that is
+embedding the SIS file. However, an embedded SIS file cannot be removed if
+another installed component has declared a <xref href="GUID-DB220677-5998-529C-BE35-0D66F588E057.dita">dependency</xref> on
+it. This depends on the security policy setting, <codeph>RemoveOnlyWithLastDependent</codeph> defined
+in the installation policy file.</p>
+
+<p>The Nested (embedding and the embedded) SIS files are processed as separate
+installations. This means that the Embedding (outer) SIS file does not propagate
+capabilities to the embedded (inner) SIS file. However, an Embedding (outer)
+SIS file can be dependent on an embedded SIS file. </p>
+<p> <b>Note</b>: If the installation of the embedded SIS fails, the entire
+installation fails. </p>
+<p>An embedded SIS file can be a partial upgrade (<codeph>PU</codeph>) or
+patch upgrade (<codeph>SP</codeph>) package type. However, the base package
+must have already been installed on the Symbian device. This implies that
+if the base package and the upgrade are both embedded in the same SIS file,
+the statement that installs the base package must occur in the source PKG
+file before the statement that installs the upgrade or patch. </p>
