It didn’t feel like sync was as reliable as it needed to be. Then they would hop onto a flight (or go someplace without connectivity) and try to access a file they thought was on their PC and it wasn’t available because it was just a placeholder.

For example, people would expect that any files they see in File Explorer would be available offline by default. “We heard a lot of feedback around this behaviour. “People had to learn the difference between what files were ‘available online’ (placeholders) versus what was ‘available offline’ and physically on your PC.

BTW, I use it in Windows 10, 11, Server 2016, and Server 2016 Essentials. “In Windows 8.1, we use placeholders on your PC to represent files you have stored in OneDrive,” explains Microsoft’s engineering general manager, Gabe Aul, in a Windows blog post. I suggest doing that first since the installer for synctoy does not always find it. In current versions of Windows 8.1 and 10, OneDrive only retains copies of certain files on your PC (unless you tell it to synchronise everything), but it seems that system has left some users baffled. Microsoft is also revamping the way OneDrive works in Windows 10.
