Re: synchronization of new files only with filemask
Did you try
-filemask="export_*>3D"?
-filemask="export_*>3D"?
You are not doing anything wrong. The file mask would only prevent download of older files. I assume there are no not-synchronized files older than 3 days.
WinSCP still needs to list the directories to tell what the file time is.
Possibly you want to exclude someexport_<date>folders completely.
export_<date> folders completely.
