## What it is
7-Zip is a free, open-source file archiver with a high compression ratio, best known for its native 7z archive format. This GitHub repository hosts the source code for the actively developed 7-Zip releases.

## Use cases
- compress files into 7z archives
- extract zip tar and rar archives
- create password-protected encrypted archives
- batch compress files from the command line
- reduce backup file sizes with high compression

## When to choose
- you need a free archiver with strong compression ratios
- you want to script archive creation or extraction on the command line
- you need AES-256 encrypted archives
- you want an actively maintained open-source compression tool

## When to avoid
- you need a graphical archiver on Linux by default (GUI is Windows-focused)
- you require commercial support or a signed license document
- you need cloud-based or distributed archiving
