Once it's successfully installed, you can start O&O DiskStat either under All Programs/O&O Software/O&O Defrag or by double-clicking the program icon on the Desktop.
Navigation Through Your Computer
In the Treeview, just as in Windows Explorer, you have a general summary of all the folders and subfolders in the drives. The Analysis of the Top list enables detection of the largest files and folders on the drives.
Analyzing your drive lets you see how much disk space individual programs, applications are occupying. The result is displayed in the form of a chart which displays the distribution of disk space. Once an analysis is complete, you can remove no longer needed data from your drive, for example, old or superfluous files.
To analyze a drive, please follow these instructions:
A chart will appear displaying the respective space usage and allocation.
The Status Bar displays a progress bar indicating the status of the analysis.
If you wish to analyze every hard disk, click on My Computer and start the analysis from there. Depending on the size of the disks, this procedure can take several minutes.
Understanding the chart
The chart displays files or folders and shows their comparative sizes. Individual sizes are shown in the labels. Smaller files and folders are lumped together and displayed as such. You can set the chart type (pie chart or bar graph) in the toolbar or under View/Chart. Each chart is designed interactively. By clicking on an individual folder in the chart, this folder will then be displayed as a chart itself.
Overview of the Hard Disk
The start screen of O&O DiskStat displays an overview of used and free space on all drives.
Select chart type
Two chart types can be selected: pie chart and bar graph. You can setup the chart type in the toolbar or under View/Chart.
You cannot uninstall programs through the Chart. This must be carried out under the Control Panel of your computer.
Deleting Superfluous Data
Upon completing an analysis, you can delete selected files and folders:
1. In the chart, right-click the file or folder you wish to delete.
2. Select Delete from the context menu.
3. The selected folder will then be deleted and placed in the Recycle Bin.
