MakeLSFX is a public domain RISC OS command line utility to enable the creation of RISC OS self extracting zip files of up to 2GBytes in size. It does this by attaching a header to unzipsfx to enable it to be used as a command file as well as an absolute (executable) file.
MakeLSFX requires the RISC OS port of Infozip's unzip, and Infozip's zip is recommended. MakeLSFX can be downloaded as a small zip file.
