'''CEBE''' (or maybe its name is '''Compress/Expand Parts''') is an executable compression utility for DOS. It was developed by Babble Enterprises. It compresses [[MS-DOS EXE|EXE]] files (to EXE), and [[DOS executable (.com)|COM]] files (converting them to EXE).<br />
<br />
It is related to [[LZEXE]], which it acknowledges; but exactly how it is related isn't clear. It might be fair to call it a hack of LZEXE.<br />
<br />
== Format details ==<br />
Compressed EXE files are identical to those made by [[LZEXE]] 0.91, except that the signature at offset 28 is "<code>CEBE</code>" instead of "<code>LZ91</code>", and the signature near the end of the file is "<code>*CEP*</code>" instead of "<code>*FAB*</code>".<br />
<br />
To compress COM format, CEBE first converts the COM file to a non-compressed EXE file, then compresses that EXE file. The intermediate file is kept around, with extension ".ORG". The intermediate format is different from that made by the COMTOEXE.EXE utility included with LZEXE. It's not clear if the intermediate format is unique to CEBE, or copied from some other COM-to-EXE utility.<br />
<br />
CEBE has a decompression feature. It tries to detect the original format (EXE or COM), and decompress to that format.<br />
