TreeSize Free shows which folders are eating up space on your hard drive

Is your hard drive getting full? The first thing you will probably do, is to delete movies, downloaded applications, etc., to free up some precious storage.

You can also use a disk cleaner application like CCleaner, to free up some space used by commonly used programs such as your browser’s disk cache, WinZip etc.

But what if you have done that, and you find that your hard drive is still quite full? The obvious option, and a very tedious task, is to manually check each and every folder, to narrow down to the one which is the mammoth. This requires a lot of time and manual effort if you have hundreds of folders and dozens of applications and games.

A more sensible option, and an efficient one too, is to use a program designed for this very purpose. This is where TreeSize Free excels. It is a free app, as the name implies, and displays the data in a simplistic User Interface, and is very easy to use.

Furst, you will need to click on Scan and select a drive to be scanned. This is one of the advantages of the app, it displays the data for each Drive individually. So this helps you analyze a particlular drive with ease. Other apps show all the data in one place and often it is very difficult to navigate such a cluttered mess.

TreeSize Free uses a Windows File Explorer-ish UI to display all your folders, and highlights the size of each one in a colored bar. The bar has many sorting and viewing options including by name, folder size, allocated size, number of files, number of folders, % of the parent folder’s size and last modified date.

You can also use the ribbon for some of these options, and additionally it features some more fine details, like view file size in KB, MB and GB which stand for the data storage units Kilobytes, Megabytes and Gigabytes, which is pretty useful for quickly accessing the largest or smallest folders easily. You can further narrow down the scan results by filtering it using certain options or simply by searching the entire tree using keywords.

The Expanded view option, allows for opening various levels of sub-folders with a click of the mouse. The Tree scan results can be printed for future reference, which is useful for comparing the folder sizes.
