When I run into a PC that has low disk space, there are usually culprits that you can point a finger at. The problem is that sometime the disk usage is not taken up in the folders that you might expect. When there is no smoking gun, I turn to my toolbox to check where the disk usage is being taken at. Below are a few tools that I use to see what is causing the issue. There are many tools out there but here are my favorites…
- WinDirStat – On start up, it reads the whole directory tree once and then presents it in three useful views:
- The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size,
- The treemap, which shows the whole contents of the directory tree straight away,
- The extension list, which serves as a legend and shows statistics about the file types.
The treemap represents each file as a colored rectangle, the area of which is proportional to the file’s size. The rectangles are arranged in such a way, that directories again make up rectangles, which contain all their files and subdirectories. So their area is proportional to the size of the subtrees. The color of a rectangle indicates the type of the file, as shown in the extension list. The cushion shading additionally brings out the directory structure. (Content provided by WinDirStat Homepage)
