Cannot move or copy a very large file from Windows 10 Client to Network Attached Storage device

A Windows 10 Client is attempting to move or copy a 270 GB file from the client to a NAS share which it has as mapped drive.  It starts and gets to approximately 70 GB in 20 minutes and then stops.  This behavior is consistent and can be duplicated.  The NAS has been shown to have an enormous amount of capacity beyond the size of the file.  There are no Quotas in use.  The Windows 10 Client has only 23 GB of size left on its hard drive.  Could this be a Client side issue?
