A 7-Zip SFX archive is a program file that can unpack the 7z archive.
There are four modules in the archive. There is a specific module for three compression methods (LZMA, Deflate, PPMd), and the fourth one compatible with all these methods. All modules have identical features.
The modified module provides a lot of options for creating SFX archives (SFX stands for self=extracting). This is what you can do with this module:
-specify the path to extract
-use absolute and relatives paths
-select between interactive, silent and hidden extraction
-control the appearance of dialog prompts and text
-simply extract the archive to the specified folder
