Create test file using fsutil Windows

The “fsutil” in windows is much similar to the “dd” tool in linux, as both of them can be used to create test files of any size.

How to:

Execute the fsutil command in the elevated command prompt. (Command Prompt > Run as Administrator)

fsutil file createnew filename file-size-in-bytes

For example to create a file named testfile of 100 Megabytes size

C:\Windows\system32>fsutil file createnew e:\testfile 104857600

File e:\testfile is created

Thats all you are done.
