chmod (Setting File Permissions)

See more FTP Examples

This example assumes your FTP server supports the "chmod" command, which typically means it must be a server running on a Linux or Unix system. The SendCommand method may be called to send arbitrary commands to the FTP server. This example sends a "chmod" command to set the file permissions.
