On Windows 10 with VSC enabled I get this kind of errors:
Failed to read the symlink Users/Jerome/AppData/Local/Packages/Microsoft.Microsoft3DViewer_8wekyb3d8bbwe/LocalCache: Unhandled reparse point type 80000018
Is it normal ?
This is a type that Duplicacy can’t handle. I don’t know where this type comes from. It is not in the official list: https://msdn.microsoft.com/en-us/library/dd541667.aspx
You can exclude this file by adding an exclude pattern to the .duplicacy/filters file.
