TreeSize Free 4.6: PDF reports and 64-bit only

TreeSize Free 4.6, a new version of the popular disk space manager, launched earlier this week with PDF reporting improvements and a move to 64-bit exclusivity.

While I switched to the excellent WizTree years ago, TreeSize Free has always been on the radar ever since the first review of TreeSize back in 2010 here on this site.. TreeSize Free 4.6 is the first release of the free version since November 2021.

The new version can be downloaded from the developer website. They push the professional version, but you get the free version download eventually. Options to install the free version or extract it to run it as a portable copy are provided. Existing users may select Help > Check for Updates to run a check for updates from within the application.


Windows users who run the operating system on a 32-bit only device can't run or upgrade to the new TreeSize version. TreeSize Free 4.5 is the last version that supports 32-bit operating systems. The limitation should not affect too many users, though.

Jam Software, the development company, notes that the switch to 64-bit only versions of Treesize Free removes memory limitations when scanning large files and "rare compatibility problems".

The interface displays the size distribution of the main disk partition, which in most cases is drive c. Options to dig into the data or switch drives are provided.

The main new feature of TreeSize Free 4.6 is PDF reporting. More precisely, the ability to create custom PDF reports. All it takes is to select a directory in TreeSize Free, then the File menu, and in the File menu  the Export > PDF File option.

TreeSize Free exports the directory as seen on the screen. Expanded subfolders are included in the report, but any folder that is not expanded is just shown without additional folders or files.

The View > Configure Columns menu adds more information to TreeSize Free and the reports that it creates. Columns such as Full Path, Author, Owner, or Last Accessed may be added, and existing columns may be removed.

Tip: the "expand" menu may be used to expand a directory quickly.

Exporting is still limited when compared to the professional version of the software.

The View menu includes another improvement. There, users find more sorting options to sort the data based on their specifications.

Closing Words

TreeSize Free is a well-designed program for Windows to quickly assess the distribution of storage on connected hard drives. The new update introduces better PDF reporting options, but these are still fairly limited.

Now You: do you use TreeSize Free or another disk space manager? (via Deskmodder)

    The portable version I currently use is 4.3 (32bit) with a size of 6MB. Now, portable version 4.6 (64bit) has a size of 40MB! What happened?

    Treesize didn’t seem to advertise 64-bit only from what I could tell
    Would have saved me time if they had

    1. Yan said on August 24, 2022 at 4:51 pm

      In fact, the Web page states specifically that it’s not 64-bit only: “any edition of Windows starting with Windows 8 / Server 2012 (32-bit and 64-bit)”.

        No, it is clearly stated below!
        TreeSize Free is now provided as a 64-bit application.
        32-bit Windows operating system, please continue to use bundled V4.5.

        >> TreeSize Free is now provided as a 64-bit application. This avoids rare compatibility problems under 64-bit operating systems, and the usable memory is no longer a limit for scanning very large file systems.

    I am interested in Martin’s article.
    My favorite is WizTree.
    However, am a very like of UltraSearch by Jam Software, so will try TreeSize Free 4.6.

      I stopped using TreeSize after learning about WizTree on Ghacks. For me, WizTree performs much beyond my expectations and quickly.

        I have tried TreeSizeFreePortable_4.60.

        TreeSizeFree is a system analysis tool similar to “WizTree”, but provides a more detailed analysis.
        However, while WizTree can provide analysis results in a few seconds, TreeSizeFree took more than a dozen minutes.
        While analyzing a system, it requires considerable system resources (RAM, CPU), so running the analysis while multitasking (keeping other apps open, such as a browser) may cause the “system to hang up”. Although it is troublesome, it is safer to terminate other applications.

        For general practical use, I found WizTree to be sufficient.
        However, TreeSizeFree is the best choice if you want a thorough and detailed analysis of your system.

        Both are useful, but the choice should depend on “what want to do”.
        In my case, I would like to utilize of both (usually WizTree, sometimes TreeSizeFreePortable).

        One consideration on WizTree vs. TreeSize Free:

        WizTree has become free only to home users. (It used to be free to both, but then changed after version 3.32.)

        TreeSize Free is still free for all users, home and commercial.

        I use TreeSize Free pretty much daily as I tend to be the head “digital janitor” for C: drive disk space monitoring alerts at my company.

    I gave up looking for the portable on the authors site and grabbed it at Portable Apps.
    Yes, its 40mb. It not asking my firewall for internet access. Whatever the change seems to be innocuous. I note that TreeSizeFreeOld.exe (dates 3rd June 2020) comes in the same download (from Portable Apps).

    As expected, a lot of the bloat on my laptop related to Dell SARemediation. Size 21.4GB (14.1GB allocated). The single time I could have used it … you guessed – it failed. To be fair, so did Windows.

    Anyone else suffering Dell clutter who wants to retain SARemediation, down size it to Minimum:

    Run C:\Program Files\Dell\SARemediation\agent\DellSupportAssistControlPanel.exe
    Click on the Settings tab
    Choose Minimum

      The portable app is in the installer, there is no separate portable app that you may download.

      1. Anonymous said on August 25, 2022 at 11:37 am

        I couldn’t see it either. It just wants to install. Do I need to extract it (e.g. with z-zip)?

      2. Martin Brinkmann said on August 25, 2022 at 12:47 pm

        I don’t have it in front of me, but I think, that after executing the installer, a prompt was displayed to switch between installation and portable use.

        Thanks. Not an obvious portable program but I’ll work it out from that.
