I have one file that is reported as having invalid characters. I presume this is the /.
2016-05-18 18:02:39: File name “OneDriveBusiness/Icon\r” (folder “xxx”) contains invalid characters; marked as invalid.
I can’t actually find this file in the file system though. Searching the whole drive for OneDriveBusiness returns no results. When I ran the sync for the first time, there was a folder with that name that had no content (other than more subfolders anyway).
Could this entry still be in the database? This is on a PC and the issue is with the scanning on that node. The message pops up each time the service is restarted.
