Ah - ExtractAllEntries looks exactly like what I need. I saw there wasn't 7zip support in the ReaderFactory and assumed that was it, but it looks like ExtractAllEntries works fine. In that case I guess...

Hi, Me again I'm afraid! I've now encountered some slightly different speed issues. Extracting using the v0.10 release from the downloads (or from NuGet) seems a lot slower than if I compile my own...

The big difference is the merging of a new 7Zip format reading. Though, the decompress should have been the same so it's odd the raw extraction time is that much slower. I ought to do some perf tests...

Sorry about the exception. I haven't extensively used Windows Store apps so I haven't noticed that. Your workaround is the style I used when testing it. If you get the callstack, it's probably simple...

No answere? on the first page on this is written "The major feature is support for non-seekable streams so large files can be processed on the fly (i.e. download stream).". But how??? :(

7Zip files aren't supported as a non-seekable stream (ReaderFactory) because the format requires seeking in order to read the contents. This is documented here:...
