Blank File Generator

Do you need a blank 512-byte file, a 1.44MB floppy disk image, or want to quickly generate a 100-gigabyte "filler" file to see how your computer responds when out of disk space? On Linux, you'd accomplish all 3 using the dd command. On Windows, however, such a command does not exist.

Blank File Generator is exactly what you need in that case! It is good for:

  • Generating exactly-sized empty files
  • Stress-testing a storage drive or network connection
  • Zero-filling or random-filling regions of the drive
  • And more!

Description and Features

Blank File Generator will generate a file on any writable disk, including a hard drive, USB flash drive, memory card, floppy, RAM disk, or network share. It can generate a blank file (filled with null or filled bytes), a text file full of spaces, or a random file.

File size can be specified in all popular units, including bytes, SI kilo/mega/gigabytes (powers of 1000), and standard kibi/mebi/gibibytes (powers of 1024). If you want to make a file that fills a drive with an advertised capacity of 4 billion bytes, for example, you can simply specify "4 SI gigabytes" instead of manually converting to the "true" gibibyte capacity.

You can specify a block size ranging from 1 byte to 256 MB; this is how much data is written at a time. This can greatly improve performance if set properly. Aim for the largest block size that will comfortably fit into RAM without paging; bigger is not always better.

Blank File Generator requires no installation, and only requires that you have the .NET Framework 2.0 installed on your system.

Oh, and did I mention that it doesn't cost a cent?
