I am using Keeping remote directory up to date Ctrl+U functionality to upload only changed files to remote directory.
My settings of Synchronization options is as follow:"Existing files only" is checked and the rest of check-boxes are unchecked.
In previous full version 4.1.9 it works as I needed. When edited file on local machine was saved, WinSCP find that file and uploaded it to the remote directory.
But in current full version 4.2.5 it is trying to upload probably all files in the directory (I did not tried what files it wants upload because I must not overwrite other files than the only one I am editing...)
Hope I describe it understandable ;-)
I guess it is a bug, isn't it? I tried to search forum but nothing similar to this topic was found.
