A file with the DYLIB file extension is a Mach-O (Mach Object) dynamic library file that an application references at runtime to perform certain functions on an as-needed basis. The format replaced the older A.OUT file format.
Mach-O is a file format used for several types of files, including object code, shared libraries, core dumps, and executables. They can therefore contain common data that multiple applications reuse over time.
DYLIB files are normally stored with other Mach-O files such as .BUNDLE and .O files, or even alongside files with no file extension. The libz.dylib file is a generic DYLIB file that is the dynamic library for the zlib compression library.
