## External Support Binaries
ENiGMA½ relies on various external binaries in order to perform common tasks such as processing file archives and extracting information from uploads/file imports, some legacy transfer protocols, etc.

:correct: Before using features such as the [File Base](/docs/filebase/index.md) or [File Transfer Protocols](/docs/configuration/file-transfer-protocols.md) it is highly recommended to install support binaries!

## Archivers
Below is a table of pre-configured archivers. Remember that you can override settings or add new handlers! See [Archivers](archivers.md).

## File Transfer Protocols
Handlers for legacy file transfer protocols such as Z-Modem and Y-Modem.

## Information Extractors
Information extraction utilities can extract information from various file types such as PDF in order to (attempt) to come up with a good default description.
