Generating Test Files of A Specific Size

While attempting to unit test the max upload size of files to CRM I needed to generates files of different sizes.  Since Windows XP came out Microsoft has included a utility called fsutil that you can run at the command line to do just this thing.

fsutil file createnew filename filesizeinbytes

1. Open a Command Prompt (As Administrator)
2. Run the following command
fsutil file createnew "c:\temp\test5.txt" 5242880

If you need to convert from Megabytes to Bytes you can use this quick converter: Megabytes to Bytes Converter
