Even in 2002, it was designed to handle massive archives, theoretically up to 16 exbibytes (2^64 bytes). Historical Context

It introduced strong hardware-level security for both file contents and encrypted headers (which hide filenames inside the archive).

While 7-Zip has evolved, the core features that defined the 7z format during its early 2000s rise include:

Unlike proprietary formats, 7z was built to be modular, allowing it to support any new compression or encryption method as they were developed.

The debut of the Lempel-Ziv-Markov chain algorithm (LZMA), which provided a high compression ratio even on the hardware of the time.

During this era, it gained attention for significantly outperforming established formats like ZIP by offering through its modular architecture. Key Features of 7z in 2002

This feature allowed multiple files of a similar type to be treated as a single data stream, drastically improving efficiency for groups of small files.

It used Unicode for filenames from the start, ensuring compatibility across different language systems—a feature not standard in many older archivers.
