DirExists Method
Checks if a directory exists on the server.
Syntax
bool DirExists(const QString& qsRemoteDir);
Remarks
Use this method to check if the RemoteDir exists on the server.
The test is performed by attempting to change the current directory to RemoteDir, and checking the response code returned by the server.
Note that this method will return false if the directory does exist but is not accessible for the client (e.g. due to a permission issue).
Error Handling
This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message.
