WinDirStat is a simple and useful program that shows a colored TreeMap representing the space occupied by all the files stored on Hard Drives.

The daily use of Personal Computer involves the download and storage of all types of files and documents. It is likely that we keep some kind of control over the number of stored files on PC, but even so, sometimes we will need the support of an external tool to carry out a more exhaustive control of the stored files.

WinDirStat (Windows Directory Statistics), analyze PC storage drives, and shows a graph representative of files and their size.

When program ends the analisys process of selected drives, the main screen will be divided into 3 main areas:

  1. File browser (top left): This zone shows a list of folders and directories found in the units analyzed. For example, if we have analyzed C:\ drive unit, we will see a list with all the directories and files of C:\. This list is ordered from largest to smallest size, so the first items of the list, will be those directories/files that are occupying more space on hard disk.
    If we browse any listed directory, the files and directories contained by that directory will be also ordered by size, so we can identify quickly and easily the files and folders that have more size.
    In addition to the name of the directory/file, the following data of each directory/file (Item) is also displayed: percentage bar of each Item, numeric percentage of each item (42%), Size (4GB), Items (number of sub-directories/files that contained by a directory), Files (number of files contained by a directory), Subdirectories (number of subdirectories contained by a directory), Last Change (last modified date of the file/directory), Attributes (the attributes of the directory/file: read, write, hidden, etc).
    When we select a directory/file from this panel, we will see highlighted an area of the TreeMap located at the bottom of the window.
  2. TreeMap (bottom): This panel is the most important of the program. It displays a series of colored rectangles that have different sizes.
    Each rectangle represents a directory/file. The rectangles may contain other rectangles (directories). If we click on any rectangle we will see the related information of that rectangle (file/directory) on the file explorer program.
    The size of rectangle is determined by the size it occupies on the disk. This way we should simply locate and select the largest rectangle to obtain more information about the directory/file.
    The colors of the rectangle represents the type of the file. For example .mp3 files can associated with yellow color, in such a way that all the yellow rectangles are representing a .mp3 file.
  3. Extension list (top right): a list with all extensions of the files found. The 12 most common extensions will be associated with a color, so we can locate easily extension color on the TreeMap, and therefore know how files with a certain extension are distributed on the hard drive.
    If we click on any of the extensions, all files with that extension will be highlighted on the TreeMap.

The program does not support network drives, so we must use it with local units.

This software is free and very simple to use, so it is recommended for all those users who wish to free up space on their hard disk, and keep it off the accumulation of unnecessary files.

Scanner is a simple program that displays a graph showing free and used space in Windows hard drives. It is quite common that hard disks run out of space and we don't know exactly which files to delete to free...
