Returns True if the file specified by RemoteFile exists on the remote server.

Syntax

 ftp.getFileExists([callback])

Default Value

FALSE

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 the getFileExists([callback]) 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.

The callback for the setFileExists([callback]) 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

This property returns True if the file exists on the remote server. It returns false if the file does not exist. You must specify the file you wish to check by setting the RemoteFile prior to calling this method.

If the class is busy or is not connected, 0 is returned.

If there is no FTP session in place, one is automatically created by first calling the Logon method.

This property is read-only and not available at design time.

Data Type
