Xceed Zip Self-Extractor Module provides 16- and 32-bit Windows self-extractor binaries that the Xceed Zip control uses when creating customizable self-extracting zip files.

The binaries can be found in the "C:\PROGRAM FILES\XCEED ZIP\SFX" directory, if you installed your Xceed Zip package in the default location.

The binaries contain all the code necessary to unzip files and display their user interface. No external DLLs, Xceed Zip ActiveX control, support DLLs, components or applications are required to run self-extracting zip files that use the Xceed Zip Self-Extractor Module binaries.

The binaries are incorporated into the zip file at the moment of its creation, or after it has been created (for example, when using the Convert method). Therefore, these binaries must be distributed with your application, because they need to be found by the Xceed Zip Compression Library in order to make the Zip file self-extracting. The SfxBinaryModule property is used to provide their location to Xceed Zip.

The XCDSFX32*.BIN file are the 32-bit binaries, which work on all Windows 95 (and up, including Windows Vista) operating systems running on Intel 386-compatible CPUs. It supports long file names, multiple-disk spanning, encryption passwords for individual files, displaying text files, running another application, and more. (See the features list for details). These binaries will not work if files are compressed with the BWT compression method.

The XCDSFXBZ*.BIN file are the 32-bit binaries, which are identical to the XCDSFX32.BIN binaries except that they can unzip files created with the BWT compression method. These binaries cannot unzip files created with the Deflate method like the XCDSFX32*.BIN binaries can.

The XCDSFX16.BIN file is the 16-bit binary, which works on 16-bit Windows 3.x as well as Windows 95/98 and Windows NT. It is more compact than the 32-bit binary, but does not support long file names and uses a custom, non-Windows 95 style directory browser. This binary will not work if files are compressed with the BWT compression method.
