This notification indicates that there are files with names that are reserved words on Windows systems. Reserved words include:
- LPT 1
While these may be acceptable on some operating systems, they may cause problems on Windows systems. Since the client may synchronize data to a number of devices, this may become an issue in the future if the folder is joined on a device running Windows.
When this notification appears in the client, you can select an new, safe name for the file and rename it.
