Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
The file contained in the FileDecompressedName property will be appended to the archive specified by ArchiveFile.
This method may only be used to add files to an existing archive. To add files to a new archive, Compress method should be used.
