Best File Sharing Method

Hello, there might be an easy answer to this but I can’t find it..

What’s the best way to access my Android Kodi folders from my Windows PC, to erase files or send movies to the Android Box memory etc..

I tried the ES File Manager/FTP method and found it unreliable (plus I rather not have to exit Kodi and turn and turn on a switch for access).

Samba, SSH, UpNp? What’s easiest to set up and most Drag-and-Drop like for an Android box?

Thanks a million in advance!
