Jibz. It supports [[MS-DOS EXE|.EXE]] and [[DOS executable (.com)|.COM]] formats. It runs on DOS, and 32-bit Windows.<br /> <br /> It has some relationship to [[X-pack for Executable]].<br /> <br /> == Identification ==<br /> Based on information from the [[file command]], compressed EXE files have bytes {{magic|8e c0 b9 08 00 f3 a5 4a 75 eb 8e c3 8e d8 33 ff be 30 00 05}} at offset 53.<br /> <br /> For compressed COM files, the byte sequence {{magic|50 a4 ff d5 73}} appears somewhere early in the file.<br /> <br /> == Software ==<br /> * [http://ibsensoftware.com/download.html aPACK download page]<br /> * [ftp://ftp.oldskool.org/pub/ANORMAL%20executable%20tools/DOSEXE%20Executable%20Tools%20Pack/packers/] → apack...<br /> <br /> == Links ==<br /> * [http://ibsensoftware.com/products_aPACK.html aPACK website]</div>
