View what is taking up hard disk space

Have you noticed that your hard drive is running out of disk space and have no idea why?  You’ve checked the common culprits such as music, pictures, and videos but find they are not responsible for the amount of space that is being used up.   I recently ran into a similar situation.  After a little research I found an excellent tool to help find the answer.

TreeSizeFree – 1MB, Developed by Jam Software

This is a very simple tool that allows you to get a visual idea of how your disk space is being used.

Here are installations instructions:

Download the installation file from here.

1.Double-click the TreeSizeSetup.exe file to begin the installation process.

2.Click Run


3.Click Next


4.Click Next to use the default installation path or modify to change the location.


5.Click Next to accept the default Icons or modify the selections to your desire.


6.Click Finish to complete the installation and Launch TreeSize Free for the first time.

At this point TreeSize Free is installed. When this window opens it will start the process of scanning the file system. This may take a few minutes depending on the size of your hard disk and the amount of used disk space.


The screenshot above shows the simplicity of the program. It shows the file system in a tree view similar to what you find in a Windows Explorer Window. The disk space used is indicated by the blue horizontal bar that is in the background of each folder. The example above you can see that Documents and Settings is responsible for approx. 14,029 Megabytes of data. You could expand the Documents and Settings folder by clicking on the + icon to the left of the folder to see the reported usage of it’s subfolders.

The Highlighted area’s in the Menu section are useful options. You can change the way the used space is reported. In the screen shot it is displayed in numerical amounts however you could click on the % button to change that to be viewed as Percentage of Disk used. You could also change the unit of measurement such as GB (Gigabytes) if you so desired.

One of the best features of this free tool is that by default, it adds a contextual menu entry. Meaning that when you right-click on a folder you can select TreeSize Free and it will analyze the folder you are in. I have found this to be very useful when I needed to find out the size of subfolders in a specific location.
