Quickly create large file on a Windows system

Question

In the same vein as Quickly create a large file on a Linux system, I\'d like to quickly create a large file on a Windows system. By large I\'m thinking 5 GB.

Answer 1

You can use the cat powershell command.

First create a simple text file with a few characters. The more initial chars you enter, the quicker it becomes larger. Let's call it out.txt. Then in Powershell:

cat out.txt >> out.txt

Wait as long as it's necessary to make the file big enough. Then hit ctrl-c to end it.
