7z Sfx Constructor -
At its core, 7z SFX Constructor is a GUI (Graphical User Interface) tool designed to create self-extracting archives using the 7-Zip compression engine. However, unlike the basic "Create SFX archive" option found in the official 7-Zip File Manager, this constructor provides granular control over hundreds of hidden parameters.
Key Differentiators:

This allows integration into CI/CD pipelines (e.g., GitHub Actions, Jenkins) to build installers automatically on each commit.
Place all files you want to package into a folder. For example:
C:\MyApp\ containing setup.exe, config.ini, and data.bin.
Click "Compile". Within seconds, your .exe will be generated. Test it on a clean virtual machine to confirm extraction paths and post-install commands work as expected. The tool leverages the official 7zSD
