I Have a 7-Zip file that contains many files inside. How can I extract one special file inside without extracting the whole archive?

Is it possible to list all the files and choose one to get in C#?

TNX!

How a file can be "special"? What is it? What's the problem?

I assume the OP meant "specific" - that's also a common language trap in German to English translation.

Ah, those translation traps... I did not get this one, thank you for explaining it to me.

Solution 1

You can extract whatever you want. You can use SevenZipSharp, a .NET wrapper of 7-Zip:
http://en.wikipedia.org/wiki/7-Zip[^],
http://sevenzipsharp.codeplex.com/[^].

Since .NET 4.5 you may use this: http://msdn.microsoft.com/en-us/library/system.io.compression.zipfile(v=vs.110).aspx
But anyway a 5!

Thank you Peter, but why do you think that Microsoft System.IO.Compression.ZipFile supports 7-zip archive? 7-zip is a separate compression algorithm.

7z is a container format. From OP tags and writing of 7-Zip instead of 7z I understood that he talking about a 7z archive container with zip compression inside, in which case we talking about a LZ77 compressed file...

Sergey Alexandrovich Kryukov 10-Aug-14 14:30pm

Yes, I understand, but there is also an algorithm. I doubt ZipFile supports this container.

Solution 2

In addition to solution 1: If you use .NET 4.5 you may use the build in ZipFile[^] class...
