WinSCP on Windows 7 SP1 (all latest Updates), WinSCP version 5.13.2 (Build 8455).
2 directories '/mnt/usb-data/entware/lib/' & '/mnt/usb-data/entware/[BACKUP]-lib/'
Want to copy contents of '/mnt/usb-data/entware/lib/' to '/mnt/usb-data/entware/[BACKUP]-lib/'.
Target directory already has files & directory structure from previous duplicate action.
When the files/dirs are duplicated the files copy to the correct place and overwrite the existing files but the directory tree ('opkg/' in this instance) is copied within the existing 'opkg' directory
[See Screen captures]
Steps to recreate:
Navigate Directory tree to '/mnt/usb-data/entware/lib/' and select all files/Directories using left click & drag down.
Right click on selection and click 'Duplicate' [Same as Shift-F5]
Set Target Remote Path: to '/mnt/usb-data/entware/[BACKUP]-lib/'
Files/Dirs are copied to 'target remote path:'.
When the '/mnt/usb-data/entware/[BACKUP]-lib/' tree is selected/refreshed the 'opkg' directory contains the new copy of the 'opkg' directory instead of being overwritten.
All other files are overwritten as expected.
