        // This is the directory structure on the local filesystem
        // from which we'll create .zip archives:
        // The root directory is /temp/filesToZip
        //
        // We have these files:
        // /temp/filesToZip/faxCover.doc
        // /temp/filesToZip/exe/Setup.exe
        // /temp/filesToZip/images/cheese.jpg
        // /temp/filesToZip/images/dude.gif
        // /temp/filesToZip/images/img3.gif
        // /temp/filesToZip/images/img4.gif
        // /temp/filesToZip/images/img5.gif

        //

        // First we'll demonstrate AppendFromDir
        // When a directory tree is appended via AppendFiles or
        // AppendFilesEx, the AppendFromDir sets the base of the
        // directory tree appended (if the file pattern contains a
        // relative path, or no path at all).

            // The DiscardPaths property removes the path from each file
            // in the zip:
