Hi Fabian,

There are several ways of accessing FTP servers.

1) Using Microsoft WinInet library, presented by WinInet.Dll file normally found on any Windows machine. This library contains a large set of Internet function, and FTP functions as well:

FtpCommand   
FtpCreateDirectory   
FtpDeleteFile   
FtpFindFirstFile   
FtpGetCurrentDirectory   
FtpGetFile   
FtpGetFileSize   
FtpOpenFile   
FtpPutFile   
FtpRemoveDirectory   
FtpRenameFile   
FtpSetCurrentDirectory  

Here is MSDN link to WinInet library

FoxPro is able to use all these functions.

2) Using Winsock API library. Wisock calls can be very efficient way to access FTP servers. Normally this library is installed on any Windows computer.

FoxPro code sample:
Winsock: retrieving directory listing from an FTP server using passive data connection (FTP, port 21)

3) Using Winsock ActiveX control. Check this link SAMPLE: Use the Winsock ActiveX Control with Visual FoxPro.

4) Using third party controls and libraries, for example the West Wind Client Tools.

6) Using the good old FTP utility -- just type FTP in Windows Start - Run. This utility is able to work in batch mode, sometimes it is good enough.
