Stable FTP client component for Delphi?

Question

I need an ftp client which is able to run stably 24/7. It needs to run in windows XP and support Delphi. It would be nice if it support SFTP. We tried Indy and Smart Ftp client before. The version of Indy we used seems to have memory leak issue and Smart Ftp DLL crash occasionally. Well, my program needs to wake up ftp client every 20 minutes (or less) all day long and those FTP client components will crash/freeze eventually. Could anyone here recommend me a really stable FTP Client Component? Thank you very much!

Answer 1

ICS (Internet Component Suite) is very good, although it doesn't support SFTP. I have an FTP client that runs every few hours daily without problems, and the author provides really comprehensive demos.

Answer 2

I've used Indy too for a similar FTP application with lots of problems and converted it to nSoftware's IP*Works! with great success and would recommend it any day. They've got an SSL version too of the components but haven't used them.
