We have a network share with the name of GIS_Imagery which has some tiff files in a sub folder on the drive. When we add these tiff images to our map it changes the drive name to GIS\Imagery upon saving the map. There are underscores in the sub folder on the drive that are not changed. Has anyone else seen this behavior? We are currently using ArcGIS Desktop 10.5.1. Is this possibly fixed in a newer version of ArcGIS Desktop?
