With FX File Explorer Plus ,You can (you can’t do this with the free version) but ,You can’t do this from The album
Once the video is in your album ,Then you have to open FX, Go to Main storage and find wyze , then to Video or Manual , Image For a Snapshot ,Go to your network, find your NAS or External drive (I have done it with both) and find the folder you want to paste it in And paste it , If there is a problem and doesn’t want to work, Rename the vid or pic file and then it should work.
