I evaluated about five different FTP OCX tools until I found Dart's PowerFTP. This is the only one which worked for me. At the beginning of building a new Windows client application for the best Fax Server 'HylaFAX', I had to resolve some problems, because HylaFAX is based on FTP but not 100% pure FTP. E.g., HylaFAX returns a '|' (pipe) as separation character. Only PowerFTP can handle this. It's very easy to use, just a few lines of code are needed to build a complete FTP client. Two times I had to ask the Dart support team. They answered immediately and helped me much.
