[edit] Format details
The generated files are highly formulaic. There are at least two, probably only two, slightly different versions:
- One made by v2.11 to 2.15. Bytes
bb 00 10 b4appear at offset 316. - One made by v2.16(?) to 3.01. Bytes
8d 1e 70 17appear at offset 316.
[edit] Identification
The first 22 bytes of a file are 0xe9 0x39 0x01 0x0d 0x0a, followed by ASCII "OPTIKS Quick View".

[edit] Software
- OPTIKS (some versions; write-only)
OPTIKS typically has a free and a commercial version. Some of the free versions refuse to save to COM format. The feature seems to work in at least free version 2.18b+.
No conversion utility is known, though you could execute the file in a DOS environment and take a screenshot.
[edit] Sample files
- LOGOPCL.ZIP (v2.11-2.15)
