"Unsupported compression method 98" error when unzipping a file. What tools support it, other than W
- by Chris W. Rea
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?
