But most others can unpack lots of archives. (Keep in mind that, IIRC, F-Prot for DOS was discontinued circa 2006, and I'm not sure if the updated data files still work or when last workable data files were available [2009??]. In other words, I don't use it anymore. But most new viruses aren't for DOS, so it's no biggie.)

I don't think Japheth intends to switch to .7z format. And there are newer encryption methods for .ZIP, though I honestly like the fact that it's easy to crack (in case someone forgets).

"Tips for selecting password length" (7z.htm , sounds naive and inaccurate but whatever)

Yeah, I forgot others gave false positives too. Still, it shouldn't be too too hard to mask the warnings, but I don't think it's worth my time, esp. since Japheth seems happy with his password .ZIP.

I don't think he will go for that. That's way too much indirection anyways, esp. for such a "clean" project.

Did you also notice that JWasm and JWlink had new releases?
