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.

fsutil file createnew filename file-size-in-bytes
For example to create a file named testfile of 100 Megabytes

File e:\testfile is created
Thats all you are done.

not intended to be comprehensive, but is a good memory refresher. You can use
the command man useradd to get the help pages on adding users with the useradd
command or the man usermod to become more familiar with modifying users with
the usermod command.
