Description
Compact Pro Archive (.cpt) is a compressed archive format used on classic Mac OS, created by the Compact Pro compression utility. It bundles multiple Macintosh files—including resource forks—into a single compressed archive, and served as a popular alternative to StuffIt in the early 1990s.
A 7Z file is a type of compressed archive that uses the open-source LZMA compression algorithm to reduce the size of the file. This type of file is often used to store multiple directories and files in a single, compressed package. 7Z files can also include strong AES-256 encryption for added security. They are commonly created using the 7-Zip utility developed by Igor Pavlov.
