'''CODEC''' (COmpressor DECompressor) is a software product developed by Telvox, an Italian company. Its main features seem to be compression and encryption. This article is mainly about its native compressed (or optionally uncompressed) archive format.

== Identifiers ==
It does not seem to have a default file extension. A comment in the [[File command]]'s database may suggest '''.dqt''', but that looks like an error caused by mistranslating [[IDArc]]'s logic.

Some third parties have abbreviated CODEC as "CDC".

== Identification ==
Files seem to start with {{magic|0x76 0xff}}.

According to [[IDArc]], this sequence could appear at offset 0 or 4, and is followed by a byte whose value is between 0x20 and 0x3f, inclusive.

Note that this format can easily be mistaken for [[Squeeze]]. There does not seem to be an easy way to distinguish them.
