Sometime ago, I reviewed WinDirStat, a free tool that helps you find files and folders occupying large space on your disk. JDiskReport can be used for the same purpose. However, it works in a different way.
WinDirStat uses a graphical representation of the directory structure to locate the big files and folders. By contrast, JDiskReport sorts filenames based on their size. Windows Explorer can sort files too, but it can only do this within a folder. JDiskReport, on the other hand, sorts files regardless of their location. This way you can get quick overview of the big files on your disk. It also offers some nice graphs displaying statistics about the size distribution and the type distribution.
On the downside, JDiskReport can’t sort folders with respect to their size. This is the feature I like most about WinDirStat. A disadvantage of JDiskReport certainly is that it requires the Java Runtime. Thus, both tools have its pros and cons. Please, also check out the comments in my post about WinDirstat for two other comparable tools.
WinDirStat averages 7 megs of ram while processing.. there is a substantially higher overhead for JDiskReport
OverDisk is another diskview tool that i had use for some time. It’s still a beta but works just fine, and that is more than i can say about JDisk and my experience with it.
I like Sequoiaview a lot better… It’s hard to explain exactly how your harddrive is represented in Sequoiaview but it’s definitely worth a look. It shows you instantly which files and directories take up the most space in a very intuitive way. Ofcourse it’s also free.
