I'm getting an error message: "unsupported compression method 98" when unzipping a file somebody sent to me. I've tried both an older version of WinZip, and 7-Zip 4.65.

I've already asked the person to avoid using a non-standard compression method and re-send the file. I know WinZip (of which they are using a newer version) has compatibility options. But, I'm wondering:

What archiving utilities, other than WinZip, support this "compression method 98"?

In particular, is there a free and/or open source tool that supports that method? If not, why not? Is the method strictly proprietary to WinZip?
