Disktective is a free porgram for Microsoft's Windows operating system that generates detailed hard drive space distribution reports.

Hard drive space analysis helps in assessing files, folders and programs based on their storage space requirements. This can be helpful in finding out where all that valuable free storage space went that was there a few weeks ago. Most computer users use these software programs to find the biggest files and folders on a computer system, to delete some or all of them to free up disk space.

We have reviewed quite a few programs that offer this functionality, among them the disk space analyzer Free Disk Analyzer, the hard drive space visualization tool Overdisk or Treesize which reports the used hard drive space by folder.


Disktective is yet another hard drive space analyzer. The portable software program can be executed without installation (it needs to be unpacked first though) making it an ideal companion for portable uses.

The program can analyze a folder or complete drive, and will display the results in a tree structure and as a pie chart in its interface after it has finished scanning the relevant parts of the hard drive.

The scan is quite fast; not WizTree crazy fast, but still fast enough to not be annoying.

The program sorts the folders by size from top to bottom in the tree structure. The size is listed in Megabytes by default, but you can change that in the options to bytes or kilobytes instead if you prefer that.

A click on sort lists options to sort the data by size instead of alphabetically. It is possible to navigate that structure to dive deeper into the folder. The pie chart that is displayed on the right side of the interface is automatically adjusted when you start to browse the tree structure.

The application supports a handful of other features. You may save reports, and import them into the program at a later point in time again. There is also an option to print the chart.

Closing Words

Disktective is a portable software program for the Windows operating system. It has not been updated in the last seven years but works fine in all Microsoft operating systems including Windows 10 (64-bit not tested). The program is available for download at the developer's website.

The program's age shows, and you may prefer to use a faster program with more options instead like the ones listed above.

Still, Disktective works fine and if you don't mind the antiquated look and feel of the program, you may take it for a whirl.
