Once you get the thing opened, you'll find a folder called "igel tsetop non tse mucearG." It's "Graecum est non potest legi" backwards, which is Latin for "It is Greek; it cannot be read."
This is a hint to change the file extension on the larger files to ".jpg," but the extension on the smaller one has to be changed to ".txt."
The first two files become images (which I'll add to this post in a moment), one called "LIGATURES" in hexadecimal code (4c4947415455524553) and the other called "AMALGAMATION" (414d414c47414d4154494f4e). The third file becomes a text file encoded in Base64, and called "SEMANTIKOS" (53454d414e54494b4f53).
Credit for all of those file and title decodings, by the way, goes to Opladybug, Jo_16_2, Killthesmiley, and islandlove. Here's the pictures and the text:

The files seem to explain the origin of the Watchers' symbol. By the way, some of us also think that the text file suggests the ceremony is done every 12 years. I know Gemma kind of turned out to not be on the up and up, but she had some truths mixed with the falsehoods.The Theta is similar to an Egyptian symbol that represents the Sun, and the Mu was derived from the Egyptian hieroglyphic symbol for water. So the Sun equals Ra...and the water equals Naunet? Or maybe Poseidon? When combined this "watcher" symbol establishes that the Order rules and watches over all that exists in between.
Theta is the 8th letter, Mu is the 12th. So that's one more 12, but the 8 = ?.
Theta was also used as an abbreviation for "Thanatos," and considered a warning of death.
Tachyon's sister was the girl who took part in the ceremony Gemma mentioned in "They Disappeared...". Gemma indicated that to have been about 11 years before that video. If that and the 12 years thing are true, then the time for Bree's ceremony might be near (especially since Gemma made that video on October 31; it's already been nearly four months since then). The Order may need her any day now. Stay alert and do heed this information. Bree kind of ignored comments from us for a while when she was being warned about OpAphid. Don't do that yourself.
By the way, diastres thought these links might be useful:
Also, tigerlilylnn noticed that the Phoenician rendering of the letter "nu"/"nun" looks like the "I" in OpAPHID's logo:diastres wrote:LIGATURES

We all hope this helps. Good luck, Beast.
Man, is he smart; he should have stayed on college, and left Bree with Jonas.
