Does anyone know how to build a script which automaticly uploads a file from a destination folder to a FTP Server? Or does anyone has something like that?

For example the commands to upload all files in a destination folder to the FTP Server, to upload one file from your own choosen destination folder and to (MAYBE??) delete a file from a FTP Server so it doesn't overwrite anything when it doesn't need to do that.

Know how, yes.. Have a script already, doubt it.

I believe that the script would require the usage of sockets, and therefore a specific address.
Please note that mIRC's file transfer options are not the best for this, as you will not obtain the maximum transfer rates.

IMO, you'd be better off using a FTP program and sending the file(s) when necessary.

Do you know a FTP program which doesn't need Administrator Access? I've found one, but it needed Administrator Access, which I don't have.

ftp.exe

I use windows explorer.
