Some screens of Hopic Explorer in action:

Some slightly scary note text gives the lie that WebDAV isn't for the layman - necessarily. But, properly configured by a geek or by an IT department, you can have access to Terabytes of data on the move on Windows 10 Mobile....

And, with access, comes all the usual file management possibilities - the remote disk(s) become 'local', effectively, and can be treated as such.

You can grab Hopic Explorer here for free from the Store.
