RED (Knowledge Dynamics)
From Just Solve the File Format Problem
.RED is an installer-archive format, apparently associated with INSTALL for DOS, and maybe other software from Knowledge Dynamics Corporation (of Canyon Lake, Texas, later San Antonio).
The identifier "RED" is probably derived from "Reduce", which is the name of a software component and a proprietary compression algorithm.
See also LIF (Knowledge Dynamics), the presumed predecessor format.
Identification
.RED files apparently start with bytes 'R' 'R' 0x01 0x29.
The 0x29 byte value is probably for the header size, so it could theoretically be different in some files. But only the value 0x29 has been observed.
