4 Ways to Learn How Much Space Windows Applications are Using

diskThere are times when you need to free up some space on your system or you just want to learn how much space each installed application is using. If you are in need of such information, there are no obvious ways to find it. You might be tempted to search for programs that help with this task. You don't need to do this though. As you can imagine, Windows 7, Windows 8 and Windows 8.1 offer this information. It's just a bit hidden and you might need some guidance to find it. We found four ways to learn how much space your installed applications are using.

Method 1: Go to Programs and Features or Add/Remove Programs

The first place where you should look is the Programs and Features panel in Control Panel, also known as Add/Remove Programs.

Windows, apps, programs, space, size

The list of installed programs (desktop applications) includes a column named Size, on the right. If you can't see it, maximize the window so that it has enough room to be displayed. Click or tap the Size column and you can see all the installed programs sorted by their size.

When you select a program, on the bottom of the Programs and Features window there is an area displaying additional information about it. This information may include also a field named Size.

There is one downside to this method though: not all applications provide this information in Programs and Features. For such programs, you can estimate their size using method 2.

Method 2: Check the Size of their Installation Folder in Windows/File Explorer

This method requires a bit more work. Open Windows Explorer (in Windows 7, Windows Vista) or File Explorer (in Windows 8 & Windows 8.1).

Go the the folder where the program is installed. Usually, this is a subfolder inside Program Files. Right click on it (or press and hold) and select Properties. Alternatively, you can select the folder and press Alt + Enter on your keyboard. The Properties window opens for the selected folder.

In the General tab, look for the Size and Size on disk entries. They share the space occupied by that application.

There is one downside to this method: it doesn't help you learn the exact space occupied by an application. You just learn the size of its installation folder. Some applications may have specific user folders where they store data. They are separate from their installation folder and, for some applications, they can be larger than the installation folder.

Method 3: Learn the Size of Windows 8 Apps from PC Settings

Windows 8 apps do not show up in Programs and Features. Also, users cannot access their installation folder without taking ownership of it and going through unnecessary complications. Luckily, Windows 8 offers an easy and exact way of learning the size of each installed app:

First, go to PC Settings. If you don't know how, read this guide: Six Ways to Access PC Settings.

Then, go to the General section. On the right, scroll down a bit, until you find an entry named Available storage.

Windows, apps, programs, space, size

Click or tap View app sizes. A list is displayed with all the Windows 8 apps installed ordered by their size.

If you see that an app you don't use takes up quite a bit of space, don't hesitate to uninstall it.

Method 4: Learn the Size of Windows 8.1 Apps from PC Settings

Even though Windows 8 apps work also in Windows 8.1, this new version of Windows offers a better way of accessing the information about the size of the apps that are installed:

First, go to PC Settings. There, look for Search and apps and click or tap this entry.

Windows, apps, programs, space, size

Several sub-sections are displayed. Click or tap App sizes.

Windows, apps, programs, space, size

On the right you will see a list with all the Windows Store apps installed in Windows 8.1, ordered by their size. The biggest apps are listed first.

If you want to remove an app that's taking too much space and you don't really use, click or tap on it to select it. Then, press Uninstall and confirm your choice by pressing the new Uninstall button that will be displayed.

That's it - you got rid of that app. :)
