cab files : Java Glossary
- cab files
Microsoft’s proprietary cabinet archive files. They have the
same function as zip and Java’s JAR files. Microsoft also uses them to
distribute software on CD (Compact Disk) ROM (Read Only Memory). They have better compression than zip files since
they are not designed to be updated. See this Microsoft tech note on how to extract data
from a cab file. This can be useful to repair a lost system file from the
original install CD.
They can be digitally signed with Authenticode certificates.
