Creates self extracting archive.
-sfx[{SFX_Module}]
Specifies the SFX module that will be combined with the archive. 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.
| SFX_Module | Description |
|---|---|
| 7z.sfx | SFX module (GUI version) |
| 7zCon.sfx | SFX module (Console version) |
| 7zSD.sfx | SFX module for installers (GUI version) |
| 7zS2.sfx | small SFX module for installers (GUI version) |
| 7zS2con.sfx | small SFX module for installers (Console version) |
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.
SFX modules for installers are included in an external package (LZMA SDK). You can download these modules from www.7-zip.org. SFX module for installers (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:
copy /b 7zSD.sfx + config.txt + archive.7z archive.exe
An optimally small installation package size can be achieved, if the installation files are uncompressed before including them in the 7z archive.
-y switch for installer module specifies quiet mode extraction.
This config file contains commands for the Installer. The file begins with the string ;!@Install@!UTF-8! and ends with ;!@InstallEnd@!. The file must be written in UTF-8 encoding. The file contains any or all these string pairs:
ID_String="Value"
| ID_String | Description |
|---|---|
| Title | Title for messages |
| BeginPrompt | Begin Prompt message |
| Progress | Value can be "yes" or "no". Default value is "yes". |
| RunProgram | Command for executing. Default value is "setup.exe". Substring %%T will be replaced with path to temporary folder, where files were extracted |
| Directory | Directory prefix for "RunProgram". Default value is ".\\" |
| ExecuteFile | Name of file for executing |
| ExecuteParameters | Parameters for "ExecuteFile" |
You may omit any pair.
There are two ways to run a installation program: RunProgram and ExecuteFile. Use RunProgram, if you want to run a program from the .7z archive. Use ExecuteFile, if you want to open a document from the .7z archive, or if you want to execute a command from Windows.
If you use RunProgram, and if you specify empty directory prefix: Directory="", the system searches for the executable file in the following sequence:
;!@Install@!UTF-8! Title="7-Zip 4.00" BeginPrompt="Do you want to install the 7-Zip 4.00?" RunProgram="setup.exe" ;!@InstallEnd@!
;!@Install@!UTF-8! Title="7-Zip 4.00" BeginPrompt="Do you want to install the 7-Zip 4.00?" ExecuteFile="7zip.msi" ;!@InstallEnd@!
;!@Install@!UTF-8! Title="7-Zip 4.01 Update" BeginPrompt="Do you want to install the 7-Zip 4.01 Update?" ExecuteFile="msiexec.exe" ExecuteParameters="/i 7zip.msi REINSTALL=ALL REINSTALLMODE=vomus" ;!@InstallEnd@!
