# 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}}`
