3. Archive File Software
========================
Digital Distortion Upload Processor comes with configuration settings to
use various archivers to handle extraction of ZIP, 7Z (7-Zip), RAR, ARJ, MSI,
TAR, GZ, TGZ, and TAR.GZ archives. If you want to use other archiver programs,
you will need to update the configuration to modify the commands used.
Digital Distortion Upload Processor will (try to) use Synchronet's built-in
archive support (if available) to extract archive files. If that fails, it will
fall back on a configured command-line to extract the archive (if configured).
Synchronet's built-in archive support will take precedence over any configured
extraction command (that is, if Synchronet itself is able to extract the
archive, any configured extraction command for that archive file type will not
be uesd).
