I am trying the first option. I have set Enable Transfer Resume/ Transfer to Temporary File Name for All Files. But When I am uploading a file its name does not change during the upload process. I am opening the second session to the SFTP server during the upload and can see that the file name is the same. Am I missing something?
Please attach a full log file showing the problem (using the latest version of WinSCP).
To generate log file, enable logging, log in to your server and do the operation and only the operation that causes the error. Submit the log with your post as an attachment. Note that passwords and passphrases not stored in the log. You may want to remove other data you consider sensitive though, such as host names, IP addresses, account names or file names (unless they are relevant to the problem). If you do not want to post the log publicly, you may email it to me. You will find my address (if you log in) in my forum profile. Please include link back to this topic in your email. Also note in this topic that you have emailed the log.
