I usually use Flie Explorer (embeded with Rom) by:
- Enter File Explorer App
- Select Remote
- Select Remote management
- Select START FTP
- you’ll get ftp address, just using FTP Program (On Windows), Mine use WinSCP (or FileZilla whatever you like).
- Enter IP address and port then connect
After that you can able to transfer/edit as you wish. Hope you can understand what I tried to explain.
