Amazon EC2 instances are just like normal computers. So, if you had a Windows computer on your desk and a Linux computer beside it, think about how you would copy files between the two computers and you can do the same thing with Amazon EC2.

Frankly, sending files 'to' a computer can be quite difficult due to security limitations and having to have some way of 'sharing' file systems, such as sharing a network drive.

A much easier way would be to have the Windows instance copy the files to an Amazon S3 bucket, and then have the Linux instance download the files from S3. You can easily copy the files by using the AWS Command-Line Interface (CLI).

This method avoids all the problems with security, sharing protocols and coping with different operating systems.
