Extract a cabinet file in metro style app.

Question

Hi all,

I have a C++ application which uses .Cab file, in my origin C++ application, i used FDI*** methods to extract those .cab file. Now i want to import all of them into Metro and create a Metro copy of my app, but i cannot find the equivalent methods in Metro. Can somebody tell me what methods i can use in the place of FDI*** methods?

Thanks,

Answer 1

Isn't CAB just a ZIP file?

I've tried but it does work in my case. I think it is because the CAB uses different compressing algorithm from the ZIP one.

Answer 3

You might be able to use some of the same c++ functions in a dll you can call from c#.  I think you should ask over on the c++ forum about doing this.

Answer 4

There isn't a CAB file extraction API for Metro style apps.

CAB and Zip are different formats. Depending on the specific file they may or may not use the same compression algorithm, but with different packaging.

The only compression API provided in WinRT is Windows::System::Compression. .Net apps can use System.IO.Compression as well. Neither of these provide CAB support.
