Random Data File Creator



Random Data File Creator is a console application to create dummy files. You can use it with a console window under Windows, the dialog Execute, Visual Studio, etc. I used it with the Run Command.

Let’s see how to use Random Data File Creator as a fake file generator:

  1. Open Run Command box.
  2. Now, type following command in the command box and hit Enter: C:\Download\rdfc\rdfc.exe <ouput path with file name and extension> <file size> [<unit> [<overwrite>]]

In the above command, you have to give full path of Random Data File Creator program file, fake filename with extension, file size, and unit as Byte, KB, MB, or GB. Overwrite is used to replace an already existing file with the same name. If a file already exists and overwrite is not added to final command, the application stops working. An example of a command to generate fake file using this software is given below:

C:\Download\rdfc\rdfc.exe LIST_OF_FREEWARE.exe 1 [kb [<overwrite>]]

If no output path is given, the fake file will be created in the downloaded Random Data File Creator folder.

During my testing, the files were being created in bytes no matter which unit is specified. So, if you need a file of size 1kb, write 1024 as file size.
