Sync does NOT follow folder symbolic links Linux -> Windows

WinSCP 5.7.6
Source Files: Ubuntu 15.10
Target Files: Windows 10

Uploaded screenshots:
  • Symbolic links option is enabled
  • Mirror sync mode
  • no symbolic link (Program-Files here) is followed during sync
No automation tools have been used, only the GUI.
If I double-click on the symbolic link within the session panel, it is followed though, which means it is recognized as such by WinSCP.

Yes, the synchronization does not follow symbolic links.

We may add a support for optionally following the links, but it's not planned atm.

Is the "Resolve symbolic links" option for syncing very different from reading? I mean, when you know the whole contents of a symlinked folder, how different is it from what is already implemented to sync it?

It would be awesome to add this feature and shouldn't represent a lot more code.

It's not that it's difficult to follow the links.
It's that WinSCP explicitly skips the symlinks when synchronizing.
Most users want them to be skipped.

I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.

Brilliant! :)
Almost perfect.
The symlinks are followed now during sync when the corresponding option is set.
However, I have isolated a very slight glitch so far: all date/time properties of synced files are correct, but for folders, they do not match; the date & time of the sync is used for the synced destination folders, instead of the date & time of the source folders.
