"Folder Size will analyze your hard drives"


Folder Size is an elegant little utility that will scan the folders on your drives and produce easy-to-digest information about the size of their contents. It may not be groundbreaking, but it does what it claims it will without any fuss and is a very light software.


The installation could not be easier and in under a minute it should be complete. Once you launch it however you will need to choose to scan one of your drives or a specific folder within your drive to get the ball rolling - and that could take a couple of minutes depending on the size of the drive or the folder.

Folder Size is compatible with Windows 98, Me, XP, 2000, Vista, 7, and 8.


In many ways the interface of Folder Size resembles Windows Explorer. It features a navigation column on the left side, and the corresponding content on the right side. Also on the bottom half of the right side are charts that analyze the usage of the selected element (along with the option to choose between pie and bar charts).

Towards the top of the interface are various icons that allow users to open and save projects, scan specific drives or folders, and even choose whether the folder sizes should be displayed in bytes, Kilobytes, Megabytes or Gigabytes.

All in all it is a relatively easy interface to get accustomed to.


Generally speaking Folder Size is very basic but that is part of the beauty of this utility and it isn't bogged down by any unnecessary baggage.

Some additional features such as the ability to print or export results to PDF, CSV, XML or even TIFF formats can be unlocked by purchasing a personal or professional license. Similarly, there is a filter for folders that can help navigating through large or cluttered drives that is available in the personal and professional versions.

Still, the free version is undoubtedly enough for most users and the quality of both the bar and pie charts that it can generate are very impressive.

UNICODE support added in version 3 is invaluable, just like the ability to scan system and backup folders, a feature introduced in version 3.4. With the later, you can now easily spot the space lost for backups or used by the OS in its system folders.


It is worth pointing out that in order for the charts to work Adobe Flash Player needs to be installed in Internet Explorer though that is not stated in the requirements and so some users may find that they have issues with it.


One of the more popular commercial alternatives to Folder Size is the Folder Size & Analyze Professional utility. While it may have more features, the free version of this software is a lot more limited and can only scan a specific amount of files and folders.

Other alternatives exist as well such as Folder Size 2.5 (an entirely different utility), but that has issues running on Windows 7 and displays information within Windows Explorer instead of in its own interface. Furthermore it doesn't have any charts.


It may not win any awards, but Folder Size is actually a very handy utility for anyone who would like to be able to see a complete breakdown of how their drive space is being allocated. The developers have mentioned that a full-fledged 'find' feature should feature in later versions, and that is something to look forward to as well.
