Adds specified files to an existing archive.
public void AppendFiles();
Public Sub AppendFiles()
When AppendFiles is called, only those files which are to be added to the archive must exist inside the collection. Note that if you call Scan or Extract, you must empty the collection before adding files to the collection to be appended.
After the file is added, the collection will be updated appropriately.
.NET Standard Notes
To call this method in an asynchronous manner call AppendFilesAsync instead. When the method completes (or an error is encountered) the AppendFilesCompleted event will fire.
