What is bom file? How to open bom files?

File type specification:

System file type icon System file type

The bom file extension is associated with the Apple Mac OS X operating system. File is created by Mac OS X Installer.

The Mac OS X Installer uses a file system "bill of materials" to determine which files to install, remove, or upgrade. A bill of materials, bom, contains all the files within a directory, along with some information about each file.

File information includes: the file's UNIX permissions, its owner and group, its size, its time of last modification, and so on. Also included are a checksum of each file and information about hard links.

Mac OS X's bill of materials format is not compatible with formats from older operating systems.

The bill of materials file appeared in NeXTSTEP to support installation. The file format was updated and extended for Mac OS X 10.0. The format was extended to support 64 bit file sizes with OS X 10.3.
