Copy files from Windows to Ubuntu/Linux

~

If you want to copy your files from windows laptop/PC to Ubuntu/Linux laptop/PC, than you can do it easiest way. If you are doing it this way than there might be some less transfer speed up to 10-20 mbps. But I am sure if you don’t have any other way than you can try this way. This way you can pause your progress and resume your transfer progress.

Follow given steps :

1) Install openssh server to your linux system

command : sudo apt-get install openssh-server

2) After installing openssh server, you can access your linux system from any other system connected with same network, you have to connect both system in same network. You can connect them via same router, wi-fi or by creating ad-hoc in one of system.

3) Install any ftp transfer application in windows, I mostly prefer filezilla to ftp transfer

4) Open filezilla in windows systsem, enter ip(ipv6) of linux system as server and user system(Linux) login credentials for ftp username and password.

5) Now you can easily move your files to linux from windows

This is the easiest way to transfer files from linux to windows.

It will work on record playback modules also, So you don’t need to setup anything more for working BBB recording API demo.
