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.

Chilkat.Zip zip = new Chilkat.Zip();

bool success;

success = zip.UnlockComponent("anything for 30-day trial");
if (success != true) {
    MessageBox.Show("Failed to unlock zip component");
    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.AppendFromDir = "c:/temp";
saveExtraPath = true;
success = zip.AppendOneFileOrDir("a/hamlet.xml",saveExtraPath);

//  To add "temp/a/hamlet.xml", do this:
zip.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();
