GetFileSize Method

Returns the size of a remote file.

Syntax

ftpclient.getFileSize(remoteFile, [callback])

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, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

Use this method to retrieve the size of a remote file. This method attempts to use SIZE and MLST commands if available, and resorts to LIST command otherwise.

Please note that this command only looks for the file in the current directory. To check for existence of a file in a different directory, change to it with ChangeDir command first, then call this method.
