Controlling Paths of Files Added to Zip

When appending files to a .zip, it can be difficult to get the paths exactly as you want them. This example describes a way that you can control the path information when adding a single file at a time to a .zip.

    CkZip zip;

    bool success;

    success = zip.UnlockComponent("anything for 30-day trial");
    if (success != true) {
        printf("Failed to unlock zip component\n");
        return;
    }

    //  Intialize the zip object by calling NewZip.
    zip.NewZip("myZip.zip");

    //  Add a reference to a file on disk to the zip object.
    //  (When appending files to a zip, the files are not actually
    //  read into memory.  References to the file(s) are added.
    //  When WriteZip is called, the referenced files are streamed in
    //  and compressed to the .zip.)
    bool saveExtraPath;
    saveExtraPath = false;
    success = zip.AppendOneFileOrDir("c:/temp/a/hamlet.xml",saveExtraPath);
    //  For brevity, this example will not check the return status...

    //  The saveExtraPath argument, if set, will cause the path information
    //  passed in the 1st argument to be saved in the .zip.

    //  To add "a/hamlet.xml", do this:
    zip.put_AppendFromDir("c:/temp");
    saveExtraPath = true;
    success = zip.AppendOneFileOrDir("a/hamlet.xml",saveExtraPath);

    //  To add "temp/a/hamlet.xml", do this:
    zip.put_AppendFromDir("c:/");
    saveExtraPath = true;
    success = zip.AppendOneFileOrDir("temp/a/hamlet.xml",saveExtraPath);

    //  The zip written here will contain hamlet.xml three times,
    //  each with a different relative path.
    success = zip.WriteZipAndClose();
    }
