Auspicious File Extensions

I got to wondering whether anyone had been bold enough to adopt .GOD for some proprietary file format. Turns out, according to the folks over at filext.com, there was once an Australian outfit called “Games on Demand” that used .godd to denote something called an “Arena Partial Downloaded Game” file, which is not so very exciting. Note that they opt for the four-letter extension with the extra terminal “D” to avoid potential blasphemy. Games on Demand is apparently no more, so maybe they paid the price anyway. The last few lines of Revelation tend to suggest that the Almighty is pretty touchy about his IP.

Which got me thinking about other provocative three-letter homonyms that might make amusing file extensions. SEX, for instance, has more than one usage: Alpha Software uses it to denote something called an “Alpha five set index,” and there’s at least one report that some Urban Chaos game files use the carnal extension.

.EAT, interestingly, appears to be unexploited. So, too, .DUG, .LOW, and .YAK. It’s kind of an amusing game to brainstorm applications that might use such extensions…
