Re: Text file specification in sftp client.

Hi again, i was reading that there is no way to do the ascii transfer, but
winscp can do that. It has a GUI, in that GUI you can specify
the file is a text file, and it uploads the file whitout any problem.

So there is a way to do that but i can find out how.
Do you have any suggestions?

thanks!
