Specifies the default action to perform when a target file already exists. However, the default action can still be changed using the ProblemDetected event.
public enum ActionOnExistingFiles
Existing files are to be always overwritten.
Existing files with different checksum are to be overwritten.
Existing files with different sizes are to be overwritten.
Existing files are to be overwritten if they are older than source files. This is strongly discouraged because modification dates are often misreported by FTP and SFTP servers, making this mode highly unreliable. We strongly recommend to use a different mode or develop a custom solution using the ProblemDetected event.
Existing files are to be renamed according the pattern "filename[number].extension". You can still change the generated name using the ProblemDetected event and the Rename(String) method.
Existing files are to be resumed if they are smaller than source files.
Existing files are to be always skipped.
Existing files are to cause the whole multi-file transfer to be canceled and an exception to be raised.
