Programs to analyze how you use hard drive space

The main cause of clutter is accumulating things without rhyme or reason and not knowing what you have stored and where. It happens in real life and also in computing.

How many documents do you have on your computer? Where are they? And songs? And videos? Why is your 500 GB hard drive asking you for help because nothing else fits? Organizing the space on your computer’s hard drive well doesn’t cost too much and will save you headaches. Because if you are careless, a day will come when you won’t know what you have kept and what you haven’t and what folder is that file in What do you need for now?

Windows File Explorer shows you the contents of your hard drive and allows you to navigate through folders and subfolders conveniently. However, it doesn’t display all the information you need or the sample separately and not in a single window.

That’s why you need a specific tool, a hard drive analyzer or disk space analyzer that will show you the occupied and free space, the largest folders and file formats and where you should take a look to delete unused files that take up space and you don’t need.


With WinDirStat you will see a list of folders and subfolders indicating the space they occupya list of file formats (images, videos, audios, documents, spreadsheets…) and a graph with colored rectangles to find out which files are the most voluminous.

These three pieces of information will help you cleaning on your computer, delete unused files and reorder lost files that you didn’t remember saving.


Another good tool to analyze the space on the hard drive and thus organize and clean files is DiskSorter, free by default and with paid versions in case you want to use it on work computer networks.

As in the case of WinDirStat, DiskSorter will analyze the hard or external drive that you indicate and will tell you the number of files in several panels, which formats are the most voluminous and what type of file occupies more. For example, the largest format can be AIV, MOV or MP4, and the file type will be Movies, Clips and Video Files.

The result will tell you if you should delete some old moviesold backups or installers of programs that you no longer use, to name just three examples of files that tend to take up more space.


Another app with graphic results is Scanner, which shows a circular graph where, in the form of colors, the heaviest or most voluminous folders and files appear.

can parse any kind of drive (internal, external, network), just like the previous programs, and from the graph itself you can choose the folder or file that you consider unnecessary and eliminate it. If you want to redistribute the files, it will be more practical to go to Windows Explorer.


With a rectangle and square data display mode, SpaceSniffer helps you understand which folders and files are taking up the most space on your drives.

Instead of a circular graph, it occupies the window with boxes of more space the more megabytes they require from your disk. In each box you will see the name of the folder or file and the amount occupied. Clicking on each box or folder will open another window showing the contentsubfolders or files, represented in the same way.

To customize the results, SpaceSniffer has a filter to view only a specific type or format of files.


If you prefer to see the analysis of the occupied space tree shapedshowing folders and subfolders from top to bottom and indicating their size, you’ll like TreeSize.

The tree view joins the column viewwhich adds more information, such as the date of the last time you used that folder or file, the percentage of space it occupies separately, the number of files included in each folder, etc.


To finish this list, another tool that combines the tree view with a pie chart, JDiskReport.

This way you can browse folders and subfolders and see at all times the space occupied by each element. In addition, the graphic view includes several tabs to also see the files ordered from most to least large, file formats and modification dates. This last option is perfect to discover unused files.
