I LOVE the synchronize feature of WinSCP, it saves me hours and hours of work when I am uploading to my huge academic website (nearly half a million files).
Sometimes before I upload new files to a section, I need to rename an image, say from RIC_123.jpg to RIC_124 (or I make a new RIC_124.jpg and delete the old RIC_123.jpg from my PC). When WinSCP shows me the list of changed or different files before I confirm the upload, files which are on the server but not on my PC are marked in red and have an "X".
Now my question is, if I tick the boxes of those files on the left, does WinSCP then delete those unwanted files for me at the same time ? Or are they transferred to my PC ?
