TreeSize Shows Oft-Missing Win10 Disk Details

One the many interesting things about Windows is the way the OS manages on-disk storage. This applies most particularly to the volume upon which the OS itself resides. In previous blog posts, I’ve recommended a SourceForge program named WinDirStat. It’s sheds considerable light on disk layout and space consumption, especially if you use “Run as administrator.” But lately, I’ve been reading quite a bit about another product: TreeSize Free from JAM Software. That program includes a built-in “Run as administrator” option. It also sheds more light on the sometimes-mysterious System Volume Information folder. Thus, TreeSize shows oft-missing Win10 disk details you may not find anywhere else.

Using TreeSize you can see 99.9% of what’s on any Windows disk, including the often-obscured System Volume Information folder, as shown here.

When TreeSize Shows Oft-Missing Win10 Disk Details, What Do You See?

As the preceding screen cap shows, you get a file list layout plus a graphical layout of disk contents that maps file size to display area. Not surprisingly, this kind of diagram is called a “treemap.” It gives the TreeSize program its name and is built into WinDirStat, too. But while WinDirStat’s treemaps look nicer, those from Treesize (and supporting listings) are more detailed.

The version of TreeSize on display here is theFree version. For-a-fee Professional ($54.95) and Personal ($24.95) versions of the program are also available. Differences among the product versions center around analysis and reporting, along with “fully configurable file search.” The latter is present in the Pro, absent in the Free, and less capable in the Personal edition.

The System Volume Information folder appears in the treemap at the upper right in dark blue. The left-hand detailed listing shows that most of its contents are “system files.” The first 8 items are over 1 GB in size. The next 9 items are over 0.5 GB. Combined, they account for about 80% of the 18.5 GB that this folder consumes on disk. Here’s a zoomed-in view of that folder’s contents.

TreeSize is intuitive and informative. It’s also easy to learn and use. I’ve already added it to my admin toolbox. You may wish to do likewise!

Where are the files?

I prefer to use Directory Report
It looks just like the MS-Explorer but always shows the folder size
