IReaderFactory has that Open I think. You don't want to put stream's IsSeekable on IArchive. You want to return true/false based on the archive/compression format. File streams are always seekable...

that's not bad idea to just have singular factory classes or something to consolidate things

> So, SevenZip doesn't have an implementation in the readers factory? is there a reason for it? This is because 7Zip requires random access to a file from my memory....

You'll have to implement that yourself if you can't guarantee Reader. It's beyond the scope of the library. I've been away for personal reasons.

Either your password is wrong, encoding is wrong or bad RAR

The issue here is that this is a SOLID archive. In RAR, you cannot randomly access a SOLID archive like a normal archive. Therefore, you should use the RarReader/ReaderFactory interface...

PRs are welcome

You'll need to be more specific. The filename and contents? What container format? Got a snippet of code?

Need a sample I guess

Ideas and PR are welcome
