Free Disk Analyzer is a free software program for computers running Microsoft Windows that will display information about the computer's storage devices. The interface looks like a pretty Windows Explorer clone concentrating on disk space usage on the computer's drives and folders.

The program displays all connected storage devices, their capacity, free space and occupied space in the beginning and it is up to the user to narrow down the data by using the computer browser in the left pane.

A click on a drive letter will start an in depth disk space analysis of that drive which will display all files and folders from that root level on sorted by their size. It is possible to sort by name, type or date modified instead. A click on a folder will load the contents of that folder and display the data accordingly.

The Windows Explorer context menu is available after a right-click on a file or folder which means it is possible to perform operations like opening or deleting them right in the program's interface.

The display mode can be switched to display only the files or folders sorted by size again. These two display modes are excellent to identify the largest (or smallest) files or folders on a specific drive or in a folder.

Files are sorted by their size and additional information like the filename, location and their relative size on the hard drive are listed. The folder display mode contains the same information plus information about the number of files and the average file size.

Links to drive cleanup and drive tools are provided for each drive letter in the general display mode. Cleanup will run the drive cleanup tool that is supplied with Windows while Disk Tools will display the disk properties of that disk.

    I’ve been using Disk Space Fan for two year. It is simple and cool. Very easy to use.
    It has a cool ringchart view to show me what eat my space clearly. And it also can scan Dropbox Folder. I like it.

    Try DiskFerret Lite. It offers a ton of capabilities that are generally only available in professional versions of disk analysis software, and it runs as an applet in your web browser. (i.e., no installation required)

    I prefer to use DiskAnalyzer Pro. It is obviously not free but gives me detailed disk space usage reports. I can even use my own filters and search criteria.

    agree that it is rather a large file, compared to TreeSize,
    I think I need to try it out some more to be really convinced

    Think I’ll stick with WinDirStat (http://windirstat.info/). Visuals look vastly superior in it.
