DiskView - the disk visualization leader

DiskView integrates completely with Windows Explorer.
The above screen-shot is a clickable visual-map - click on the components to learn more about them.

 

The DiskView Visualizer in the bottom right shows the currently selected folder in Explorer in the form of a graphically rich pie or bar chart. System files/folders have a distinctive pattern, and in this case are taking up a lot of disk space!

 

The DiskView Folders pane shows the relative size of folders with small bars representing the size of each folder as a percentage of the total disk size, or of its parent folder's size.

 

You can arrange the DiskView Folders tree-view by size or alphabetically.

 

The DiskView Toolbar at the top allows you to toggle the DiskView Folders and Visualizer panel on and off.

 

The summary view on the right shows what percent of the total disk-space(white bar) is filled(yellow bar), and what percent of it is being occupied by the current folder(blue bar). It also shows icons for each local disk on the system showing their current disk space usage.

The bar chart visualization mode of DiskView Visualizer shows the 'size on disk', percent of space occupied and relative size of the files and folders.

The disk health visualization mode of DiskView Visualizer shows the disk health parameters reported by S.M.A.R.T. As the pointer (value) is in the green zone(more than threshold), disk health is good. If the value is in the red zone for a pre-failure condition, an immediate backup is strongly recommended as disk failure is imminent.

Net Disk Usage summary for all local disks is reported on navigation to "My Computer"

DiskView Size and Relative Size columns added to details view of Windows Explorer. DiskView fills in the size of folders while Windows Explorer leaves them out.

Shell context menu is integrated with the Pie and Bar charts - right click the pies as if they were files/folders.
Note that files have a 'dotted' appearance and folders are plain shiny pies. You could click on the top circle showing total size and go to the folder above. Click on the folder-pies and navigate into them!

File fragmentation is reported visually. If your commonly used files are getting fragmented, it's time for defragmenting and speeding up your computer!
