This module must be placed in the same directory as the 7z.exe.

If {SFX_Module} is not assigned, 7-Zip will use standard console
|
|
SFX module 7zCon.sfx.</P>

<P>SFX module can unpack 7z archive or 7z multivolume archive. For example,
|
|
if you have name.7z or name.7z.001 archive, just rename sfx muldule to name.exe and place
|
|
to same folder with archive.</P>
|
|
|
|
<H4>SFX modules for installers</H4>
|
|
|
|
<P>SFX modules for installers are included in an external package (7z_extra). You can download
|
|
these modules from www.7-zip.org. SFX modules for installers (7zS.sfx and 7zSD.sfx)
|
|
allow you to create your own installation program.
|
|
Such a module extracts the archive to the user's temp folder, and runs a specified program,
|
|
and removes the temp files after the program finishes.
|
|
A self-extracting archive for installers must be created as joining the following files:
|
|
SFX_Module, Installer_Config (optional), 7z_Archive.
|
|
You can use the following command to create an installer self-extracting archive:</P>
|
|
<PRE class="example">
|
|
copy /b 7zS.sfx + config.txt + archive.7z archive.exe
|
|
</PRE>
|
|
|
|
<P>An optimally small installation package size can be achieved,
|
|
if the installation files are uncompressed before including them in the 7z archive.</P>
|
|
|
|
<P><SPAN class="filename">-y</SPAN> switch for installer module specifies quiet mode extraction.</P>
|
|
|
|
<H4>Installer Config file format</H4>
|
|
<P>
|
|
This config file contains commands for the Installer. The file begins with the string
|
|
<B>;!@Install@!UTF-8!</B> and ends with <B>;!@InstallEnd@!</B>.
|
|
The file must be written in UTF-8 encoding.
|
|
The file contains any or all these string pairs:
|
|
<P>ID_String="Value"</P>

<P>You may omit any pair.</P>
|
|
|
|
<P>There are two ways to run a installation program: <B>RunProgram</B> and <B>ExecuteFile</B>.
|
|
Use <B>RunProgram</B>, if you want to run a program from the .7z archive.
|
|
Use <B>ExecuteFile</B>, if you want to open a document from the .7z archive, or
|
|
if you want to execute a command from Windows.</P>
|
|
|
|
<P>If you use <B>RunProgram</B>, and if you specify empty directory prefix: <B>Directory</B>="",
|
|
the system searches for the executable file in the following sequence:</P>
|
|
<OL>
|
|
<LI>The directory from which the application (installer) loaded.
|
|
<LI>The temporary folder, where files were extracted.
|
|
<LI>The Windows system directory.
