FileExists Method

Checks if a file exists on the server.

Syntax

bool FileExists(const QString& qsRemoteFile);

Remarks

Use this method to check if RemoteFile exists in the current remote directory. This method attempts to detect file existence using SIZE and MLST commands first, and falls back to LIST command if they are not available.

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.

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.
