Re: Deleting unwanted files when synchronizing
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 ?
Yes.
See https://winscp.net/eng/docs/ui_synchronize_checklist#information_displayed
Though even better is to tell WinSCP that the new and the file are actually the same and the difference can be resolved by a rename (to save the upload):

The next version will show hints for the icons:
