Directory Size Calculator

windows softwareThe best way to free up some hard drive space is to sort the files and folders of that hard drive by size. Windows Explorer is able to sort the files by size but not the folders. It is possible to get the folder size of one folder by right-clicking on that folder and selecting properties but that's not practicable if there are more than a few on that drive.

Windows Explorer alternatives are an option as they usually provide the feature as are programs that have been solely designed to sort files and folders of a partition or hard drive by size. Directory Size Calculator is a free portable software program that belongs to the latter category of applications.

The applications clean interface is divided into two levels. The upper level is displaying the folders and subfolders that are located in the root folder that has been selected by the user. The size of each folder is displayed in Megabytes and as a total percentage of the space. The lower level lists all files of the selected folder including their size and percentage of the total space. This makes it easy to locate the largest files and folders on a computer system.

A right-click on a file or folder opens a context menu with options to move or delete the directory or file, open it in Windows Explorer or export the data in an XML document. Directory Size Calculator should be compatible with most versions of Microsoft Windows. The developer is providing binary and source downloads on his website.

    a better app for this i find is ‘folders report’ (Folrep) @

    great piece of software – i use it regularly… particularly useful when users need an entire print of their directory structure. (or to show folder sizes and subfolders) even saves reports as .html files…

    WinDirStat is the best I have found. Full of features and easy to use.

    Another utility is Directory Report
    It looks just the MS-Explorer but always shows the directory’s size
    Can output to XML, Text, CSV and HTML
