Editor's Corner

If you've got a PC or laptop running Windows 8 or later and your system has a solid state disk (SSD) drive in it, you've probably discovered that you're running out of disk space. But before you start deleting large files or moving data off of your system, you should first get an accurate assessment of who the main culprits are that are eating up all the space on your disk. For various reasons the in-box tools in Windows are of limited usefulness for this purpose, so in this week's newsletter we'll look at a few tools you can download that can help you get a more accurate picture of disk usage on Windows-based systems. We also have other news, some great tips, and links to lots of other fun and useful stuff, so read on!

Speaking (at least tangentially) of taking up space, did you know that studies suggest you can increase your Alpha Male dominance by spreading out your arms and legs so you take up more space? Well, I can top that--check out this Dilbert comic strip:


Sorry girls, but we know you're already the dominant species anyways.

What's filling up your disk?

In the old days if you wanted to find out how much disk space was used by a folder, you basically had two ways you could do this in Windows:

Both methods worked and the results were always accurate. And since users were almost always local Administrators on legacy versions of Windows, they could easily use either of these tools to poke around on their systems to find out what file or folders were occupying the most space.

But then Windows Vista came along and introduced some new NTFS file system features like hard links, junction points and symbolic links. These new features complicated things because the in-box file system tools (Windows Explorer and the DIR command) were now no longer accurate in certain circumstances. A good example of this is the Windows Component Store, which is the folder C:\Windows\winsxs on Windows Vista and later. This folder stores old versions of operating system components that have been updated so you can rollback in case an update causes problems with your Windows installation. So while you might think that it's your bloated winsxs folder that's eating up all the free space on the SSD in your Windows 8.1 laptop, it's probably something else causing the problem.

But if poking around the file system using Windows Explorer or DIR will no longer help you find the space-eating culprit on your system, what can help you diagnose the root cause of your problem? There are several free tools out there you can try to use for this purpose, so let's look at them briefly.

Disk Usage v1.5

Disk Usage (du.exe) is a simple command-line tool that can report on the disk space usage for a volume or directory you specify. By default it also recurses directories and shows the size of the directory and all its subdirectories as well. The tool is one of the Windows Sysinternals tools created by Mark Russinovich, and you can download it for free from here:


For example, when I run du.exe against the winsxs folder on my system I get this:

c:\tools>du c:\windows\winsxs

Du v1.5 - report directory disk usage
Copyright (C) 2005-2013 Mark Russinovich
Sysinternals - www.sysinternals.com

Files:        55129
Directories:  14387
Size:         11,514,221,662 bytes
Size on disk: 11,698,106,368 bytes

If I run this with the -u parameter to count each instance of a hardlinked file in the folder, I get this instead:

c:\tools>du -u c:\windows\winsxs

Du v1.5 - report directory disk usage
Copyright (C) 2005-2013 Mark Russinovich
Sysinternals - www.sysinternals.com

Files:        57548
Directories:  14387
Size:         11,815,059,415 bytes
Size on disk: 12,004,462,592 bytes

By the way, check out the Recommended For Learning section of this newsletter for some resources that can help you learn how to use the various Windows Sysinternals utilities.


While du.exe is an accurate tool for analyzing your file system, it's not very user-friendly. For example, if you want to analyze your whole C: drive you could do this:

du -u -v > output.txt

When you open the text file in Notepad however, you'll have a ton of information to plow through. Wouldn't it be nice to have something smarter than du.exe?

Of course, and that's exactly what WinDirStat is: a free, open-source disk usage analyzer that has been around since the days of Windows 95 and which can be downloaded from here:


When I run WinDirStat against the C: drive of the Windows 7 desktop PC that I do most of my writing work on (yes we're still running Windows 7 in our offices though do I have a laptop running Windows 8.1 for working offsite) I can see immediately that most of my disk space is being occupied by user profile folders:

Figure 1: User profiles make up 40 percent of disk usage on this system.

What's really helpful in my case however is the top right pane of WinDirStat which when expanded looks like this:

Figure 2: There are 16 gigs of FSD files on my hard drive.

What the heck are FSD files? These are files in the Office Document Cache and they're used by the Microsoft Office Upload Center to allow you to see the state of files you're uploading to SharePoint. The files are saved in the Local subtree of the AppData folder in your user profile:

Figure 3: Where the Office Document Cache files are stored in your profile.

Now I'm thinking these files can probably be purged since they date back to a project last summer when I was accessing a customer's SharePoint site over VPN. To purge the cache, I start by launching the Microsoft Office Upload Center on my computer and opening Settings:

Figure 4: Configuring the Office Document Cache.

I then click Delete Cached Files to purge the Office Document Cache on my system. I should probably also select the "Delete files from the Office Document Cache when they are closed" option because I really shouldn't be keeping local copies of customer files on my computer anyways. Note that your cache might not be purged immediately as this thread on the TechNet Forums explains:


For more information about Office Document Cache settings, see here:



The third utility I want to mention here is one that one of my colleagues recently recommended and which I hadn't been aware of until recently. This tool is SpaceSniffer, which presents disk usage in the form of a visual treemap that enables you to quickly see the biggest folders and files are on your volumes. You can download SpaceSniffer for free here:


I've only started to play with SpaceSniffer and I must say it's awesome. You can double-click on each box in the treemap to drill down and see what the folder contains. For example, here's what the Office Document Cache folder looks like on my system:

Figure 5: The Office Document Cache displayed in SpaceSniffer.

Be sure to run SpaceSniffer and these other tools as Administrator (right-click and select Run As Administrator) in order to get an accurate count of all the files and folders on your system volume. And by the way, if any of you readers have any tips or gotchas you'd like to share concerning Du.exe, WinDirStat, SpaceSniffer, or any other disk usage analysis tools you want to recommend, feel free to email us at [email protected]

How to get the ADK for Windows 10 TP

If you're planning on deploying Windows 10 once it comes out, you'll want to start getting familiar with the deployment tools like the Windows Assessment and Deployment Toolkit (Windows ADK or just ADK) a set of tools you can use for building and delivering standard images together with other tools like the Microsoft Deployment Toolkit (MDT) and System Center Configuration Manager (SCCM). Finding the ADK for Windows 10 Technical Preview is a bit tricky however, so here's a summary of the steps you'll need to follow:

Start by visiting the Windows 10 Hardware Development site found here:


Click the link "Download Windows 10 Kits, Tools, and Code Samples" near the bottom right. Sign in as a Windows Insider (or click Get Started if you're not one yet) and under the heading Build Great Hardware click the link "Install the Hardware Development Kits". Then under the heading Customize, Assess, and Deploy Windows, click the link "Download the Windows ADK for Windows 10 Technical Preview" to run adksetup.exe and begin the download. Note that the ADK is about 6 GB in size so it may take a while to download.
