Sometimes when we buy a new hard drive or flash memory you need to try to know the speed of file transfer, but you may not have large files on your computer to do so, and to solve this problem in this post in a way that does not know the majority enables you to create fake files in large sizes.

The method is very simple where we will rely on the command prompt which you can access by pressing the Windows logo and the letter R and typing CMD in the window RUN, after opening the command prompt you will write the following command
fsutil file createnew filename length
If you would like to create a text file or .png in case you want to create an image, length will also be replaced by the size of the file by bytes. For example, if you want to have a file size of 5 GB, you will write 5368709120 and in the end you should It should be like this
fsutil file createnew fakextext.txt 5368709120
