Disk Tools

File generator, drive speed, free-space wipe — in one package.

The toolkit used by labs, IT publications, and hardware-review sites for disk benchmarking.

Disk Tools bundles four sharp utilities: a file generator that produces up to 2.1 billion files of any size, a secure free-space wiper, a read/write speed benchmark, and a free-disk-space inspector.

File Generator

Create up to 2.1 billion files, each up to 10 TB. Configure:

  • How many files to generate
  • Size of each file
  • Content (random bytes, user-defined text, single byte)
  • Filename pattern (user-defined, incremental, random)

Useful for disk stress testing, server testing, network performance testing, and programming work that needs a known-shape data set.

Free-Space Wipe

When you delete a file Windows does not actually overwrite the data — it just marks the disk space as free. Undelete and forensic tools can usually recover it. Free-Space Wipe fills every byte of unused space on a partition with garbage, so previously-deleted files are unrecoverable.

Drive Speed

Read and write speed benchmark for any drive — HDD, SSD, USB stick. Compare drives side by side. Defragment before benchmarking spinning drives for representative results.

Free Disk Space

One-screen overview of free space on every drive and partition. The detail Windows hides under five clicks, exposed in one view.

Merge Files

Merge every file in a folder into a single file, with a custom separator between them. Works for any file type.

  • Four tools in one portable executable
  • File generator scales to 2.1 billion files / 10 TB each
  • Secure free-space wipe defeats recovery tools
