How To: Create a new file of a specific size

This is Syed Aslam Basha here from Relationship experience division (RXD) team.

For one of my application testing I required files of specific different size starting from 1 MB to 1.5 TB. Using fsutil you can easily create a new file of a specific size as shown below:


 fsutil file createnew <path with name of file> <size in bytes>


For example the command to create one GB file is:

 fsutil file createnew d:\OneGB.txt 1073741824
