Automatically running a program for files in a folder

Hi, I have a folder which has 36 zip files. Each zip file ,if extracted, will have 5 files out of which one file (extension .HDF) is relevant to me. I have made a program which can run one HDF file. Without repeating the operations of extracting file and changing the name of .HDF file in my program every time, is it possible to make a new program where I just specify the path of folder and matlab extracts all the files and run the program which I have made? Thanks.

Most probably, YES, with something like

    sad = dir( fullfile( 'your_folder', '*.zip' ) );

    for s = transpose( sad )
        filenames = unzip( fullfile( 'your_folder', s.name ), outputdir );
        hdf = position of hdf-file in filenames
        your_program( fullfile( outputdir, filenames{hdf} ) )
        delete( fullfile( outputdir, '*.*' ) )  
    end
