I'm trying to move SharePoint files within the same site, but between two different document libraries. Unfortunately, when I go to move, I keep getting the following error "The file or folder contains properties that will be lost at the new destination." And, the button to "move anyway" shows up.
When a file is assigned to a content type, the metadata was linked to the file and not the library. The Content Type must be on the destination Library.
You had to first add the Content Type to the new library in order not to lose the metadata. Then you can move your files without getting this warning.
