# 7za
> File archiver with a high compression ratio.
> Similar to `7z` except that it supports fewer file types but is cross-platform.
> More information: <https://manned.org/7za>.
- [a]rchive a file or directory:
`7za a {{path/to/archive.7z}} {{path/to/file_or_directory}}`
- Encrypt an existing archive (including file names):
`7za a {{path/to/encrypted.7z}} -p{{password}} -mhe={{on}} {{path/to/archive.7z}}`
- E[x]tract an archive preserving the original directory structure:
`7za x {{path/to/archive.7z}}`
- E[x]tract an archive to a specific directory:
`7za x {{path/to/archive.7z}} -o{{path/to/output}}`
- E[x]tract an archive to `stdout`:
`7za x {{path/to/archive.7z}} -so`
- [a]rchive using a specific archive type:
`7za a -t{{7z|bzip2|gzip|lzip|tar|...}} {{path/to/archive.7z}} {{path/to/file_or_directory}}`
- [l]ist the contents of an archive:
`7za l {{path/to/archive.7z}}`
- Set the level of compression (higher means more compression, but slower):
`7za a {{path/to/archive.7z}} -mx={{0|1|3|5|7|9}} {{path/to/file_or_directory}}`
