If my Teams Documents are synced to my system. my System gets attacked by any virus which renames all the file, including my team file which gets synced with my teams. In this case, How I can recover the old name of my files?
One Possible way is to open the Document Library in SharePoint and check the Activity History of the Document and rename the file. But for a large number of files, this method is very slow.
Currently there isn’t an easy way. Probabaly a 3rd party too or script. However Microsoft will be releasing restore points with Sharepoint soon that will allow snapshot restore of entire libraries etc. to any point in time just like OneDrive is about to get. Not sure on timeline but it’s not too far out.
