in thread help with unraring

I want to extract one file perform some operation and then extract the next which is not possible by 7zip as it would extract the full content of rar file in one go

    Unless there is some dependancy you haven't disclosed -- say, for example, that the content of the file currently being processed determines which file to extract and process next -- your desire to extract them one at a time is not a war-stopper; it is merely one alternative approach:
    Pseudocode: un7zip ($archive); @todo = readdir (extracted files); for $todo(@todo) { process as you wish... }

    Most decompression/compression programs support extracting/adding individual files from/to an archive. This should work, but I only tested it against a .7z file. But I am not aware of any reason why it would not work with .rar files.
    7z.exe e <archive_name.rar> <path_to_file_in_archive>
    Here's an example. Given a 7-zip file called test.7z, containing:
    test test/foo test/bar
    This should extract just 'bar' to your current working directory:
    7z.exe e test.7z test/bar
