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

PowerShell one-liner to create a file in C:\Temp to fill disk C: leaving only 10 MB:

[io.file]::Create("C:\temp\bigblob.txt").SetLength((gwmi Win32_LogicalDisk -Filter "DeviceID='C:'").FreeSpace - 10MB).Close
