Version 1.3.1.1

  • Enter key was not working when a path or UNC was keyed into the address bar.

Version 1.3.1

  • Added a screen overlay on data views to indicate when view is filtered.
  • Delete operation failing on 64 bit systems.

Version 1.3.0

  • This version runs as a native 64 bit process on 64 bit Windows platforms. DiskFerret has always run on 64 bit Windows operating systems, but it ran as a 32 bit process under Windows' WoW64 subsystem on 64 bit systems. Now, DiskFerret runs as a 64 bit process on 64 bit systems, and as a 32 bit process on 32 bit systems. If you manage a variety of systems and need to install and run DiskFerret on any or all of those systems without the hassle of managing different installers for each platform, the DiskFerret installer makes it easy because one installer handles both x86 and x64 systems.
  • An address toolbar has been added to the main user interface which provides a method for power users to enter a drive, folder, or network share UNC to quickly navigate to a specific location in the file system. It also serves a dual purpose of providing a history of locations that you have visited during a DiskFerret session and lets you select those locations from the address drop down list to quickly navigate back to a previous location. The address bar also provides a method to access file locations that would otherwise be hidden in the file tree, such as when local disk drives are hidden by a Windows group policy.
  • In many cases when you analyze disk usage you need to visually inspect a file to determine whether it should be retained or deleted. DiskFerret now makes it easier by providing the ability to "launch" a file from any data view by double clicking the file, or by clicking the right mouse button and selecting the Open menu item from the context menu. When a file is opened from a detail view, or a chart view, DiskFerret uses the Windows file associations to launch the associated application and opens the file so that you can view the file immediately without having to manually open the file via the application or manually navigating to it via Windows Explorer.

Miscellaneous enhancements and fixes:

  • The Cleanup Wizard is now available in DiskFerret Lite. DiskFerret Lite is free! It runs as an applet in your browser and doesn't require any installation, and includes all of the functionality of the full version of DiskFerret, except analyzing network drives and file ownership.
  • The number of folders and number of files for the selected drive, share or folder are now displayed in the data view status bar.
  • A "Select all" menu item and keyboard accelerator has been added to edit menu for convenience.
  • Several memory leaks were corrected.
  • DiskFerret Lite has been modified to use native Windows calls for file size analysis to improve performance. Scan times for DiskFerret Lite are now almost as fast as the full version of DiskFerret.

Version 1.2.2.2

  • Fixed a problem with an exclude filter on hidden attributes that was also hiding drives in the tree view.

Version 1.2.2.1

  • DiskFerret Lite should not follow Windows shortcuts (links).

Version 1.2.0

Version 1.2.0 has the ability to save scans. After scanning a drive, folder, or network share you can save the scan to disk and open it later, or share the scan with a coworker.

This version also includes a Cleanup Wizard that guides you through a few simple steps to clean up junk files and remove temporary internet files, cookies, internet and desktop history in order to protect your privacy.


Computer Privacy Issues are gaining a lot of attention recently, and for good reason. Internet fraud and identity theft is increasing rapidly, and there is more awareness and concern about online privacy issues. The recent Wall Street Journal's investigative report, What They Know, found that the top 50 US. websites installed an average of 64 tracking tools on visitors' computers. Of those files, an average of 44 were installed by outside companies - the rest were installed by the websites themselves. Many of those so-called third party companies are in the business of tracking consumer behavior across the Internet. It is time to take these things seriously.


Today, most of the attacks against your privacy and identity take place through the data stored on your own computer. A lot of personal and private data can be extracted by a determined hacker once they gain control over your computer. Should you leave data on your computer that hackers can find? Don't like the idea of websites tracking you forever after you've visited their websites? Concerned about other users with access to your computer looking at your working and web browsing activities? DiskFerret's Cleanup Wizard can help. By answering a few questions the Cleanup Wizard guides you through the steps necessary to remove space wasting junk files and cleans your desktop and Internet Explorer temp files, cookies and history.


A big privacy concern that most users are not aware of is that clearing Internet Explorer's cache via Internet Explorer Tools gives users a false sense of security. Internet Explorer creates a file named index.dat that functions as a redundant database of information such as web URLs, recently opened files and search queries. This file cannot be easily erased because it is always open when Windows is running. Open files are considered "locked" and cannot be deleted in any way when they are open. Even after a user has cleared their temporary cache, either manually or via Internet Explorer's Tools, the information in the index.dat file is not removed and the file is not deleted. If not deleted the index.dat file provides information about your working and browsing habits in the same way that temporary files do to anyone with access to the computer. DiskFerret's Cleanup Wizard has the technology to delete the index.dat file. Just answer a few questions, and your privacy is protected. Easy, and fast. Try DiskFerret for 30 days, for free.


Version 1.1.0

Version 1.1.0 contains two new charts. A treemap, and a concentric ring chart, both of which provide a single view of a folder and all of it's subfolders and files. These charts make it easier than ever to identify the space hogging files at a glance. Other enhancements in this version include reducing memory consumption to 50% of previous levels, and reducing the size of the installation package by more than 85%. If you are new to DiskFerret, download our latest version and check it out. If you are aleady a licensed user of version 1.0.x you can download and install version 1.1.0 at no additional fee.
