ReaderFactory.Open does not check for SevenZipArchive #491

Open matthewDDennis opened 4 years ago

matthewDDennis commented 4 years ago

Thus when using ReaderFactory.Open I get an error of

Cannot determine compressed stream type. Supported Reader Formats: Zip, GZip, BZip2, Tar, Rar, LZip, XZ

7Zip isn’t supported as a Reader. 7Zip the format sucks because you can’t stream it. You need random file access to properly extract data. You have to use ArchiveFactory.

Yeah, I figured it out, but had to read the source code. Are there docs?
