Both my PC and my android box are on the same wireless network, if that is any help. I know I can use chromecast to cast files to my tv, or share a folder and have apps like kodi access them... but I am wondering if there is a way to just send the files directly to the android box... I've got a 128GB usb added as 'internal storage' on the android box, and well... my PC gets full really fast. I know I can do it with USB stick, which is what I've been doing all this time, but I'm wondering if there is a way to just wirelessly send the files to the the android box via the network, so that I don't have to keep the files on my PC.
I did this a long time ago but recently had to reformat my PC so I lost the mapping. I've been having trouble getting to reconnect again, so while I can't help at the moment I'll stay posted to this thread in case I ever get it mapped again.
EDIT: so I ended up just re-enabling SMBv1 on my Windows machine to gain access to the SMB service running through Plex Media Server. I really just need it enabled to transfer some files from an old drive to the new drive so I'll be able to disable it afterwards again. Apparently it's outdated and insecure and Plex needs to update their server app to use a better protocol. To map the drive I just set it to drive S:\ and used the login info found via Settings -> Storage &reset -> Transfer files over local network
