 # The "PKSFXjr" format supported by v1.10+, selected using ZIP2EXE's <code>-j</code> option. This is also known as "Mini" or "Junior" format. PKSFXjr files have a smaller size overhead, but limited features. Only a single compression method is supported (Implode or Deflate, depending on the version).

+Most versions of [[PKZIP]] for DOS include a ZIP2EXE.EXE utility that converts a ZIP file to a self-extracting archive. The files it creates can perhaps be put into four classes:
 # The format made by PKZIP 0.90 to 1.02. Creating such files involves a convoluted method whereby the executable stub is copied from the original distribution file (e.g. PKZ090.EXE). The user must enable the feature by using the included MAKESFX.COM utility to generate the not-included PKSFX.PRG file required by ZIP2EXE.EXE. Every self-extracting EXE then begins with the bytes in PKSFX.PRG.
 # The "standard" format made by v1.10. The executable stub seems to be significantly different from earlier versions. Also, as of v1.10, the MAKESFX.COM method is no longer used.

 A self-extracting ZIP archive usually consists of an "executable stub" segment, followed by the part of the file containing the ZIP-formatted data.
-In [[EXE]]-based formats, the ZIP data is usually placed in the "overlay" segment. So, signature bytes <code>'P' 'K' 0x03 0x04</code> usually appear at the start of the overlay segment, sometimes after a padding byte.
