Invalid file format when opening multi-part archive #7

Open cheshire137 opened 10 years ago

cheshire137 commented 10 years ago

I'm trying to open a multi-part 7zip archive. I have tested opening the archive in 7zip in Windows and it opens fine, so the archive is valid.

>> path = 'test-multi.7z.001'
>> File.open(path, 'rb') {|file| SevenZipRuby::Reader.open(file) {|szr| szr.extract(:all) } }
StandardError: Invalid file format. open
  from /Users/me/.rvm/gems/ruby-2.0.0-p353/gems/seven_zip_ruby-1.2.0/lib/seven_zip_ruby/seven_zip_reader.rb:227:in `open_impl'

There are two files, test-multi.7z.001 and test-multi.7z.002. When I extract 001 in Windows in 7zip, it automatically grabs part 002 when it needs it and extracts the whole archive.

Thank you for your report.

Currently, this library has not supported multi-part archive yet. Multi-part will be supported by the future version.
