This notification indicates that there is a folder/ file whose name contains words which are reserved on a Windows operating system. These reserved words are:
- LPT 1
While including these in a file/ folder name may be possible on other operating systems, they may cause problems on a Windows operating system. Since the client synchronizes data from various devices, it may become an issue if the folder/ file is transferred to a device which has a Windows operating system.
If this notification appears in the client, you simply have to rename the folder/ file and select a new name.
