HDGraph 1.4

HDGraph shows disk space utilization as a pie chart

HDGraph 1.2.0 is a tool that displays graphically the hard disk space usage.
The program shows all the directories and subdirectories of your hard drive(s) on a single graph, allowing to see the largest directories at a glance.

When the program launches, it gives you step by step instructions to interact with it.

You must first type the drive you want to graph in the top combo box.

Then, press the "Scan/Refresh" button.

The program will then read the data from the chosen unit, and will display the graph of that unit, after some time.

The graph will show you a colored pie with blocks representing the different folders in your drive. That way you can know graphically which folders are using space in your drive. You can decide, then, if you delete or keep the content of these folders. Sometimes, you experiment a sudden loss of disk space. HDGraph lets you know how that space become used.

HDGraph is usually unable to read some data in your disk, as unreadable files, lost space or folders and files whose path is bigger than 255 characters.
