WinINet dont overright

Hi all;

I am using the WinINet API to upload my files. What i want is to prompt the user if they want to ovewrite the file or skip the upload process. My problem is how do i know if the file is already on the web server? the way i set it up b4 was i used FtpOpenFile() to first see if the file was there, and if it was prompted the user if they would like to continue. However i found this to be twice as slow because of the extra message to the server. So i was hoping i could just use FtpPutFile() with a dwContext, however i cant seem to find one. Any advice is greatly needed. Thanks.
