Checking hard drive capacity and folder size on your Mac laptop
About this article
This article includes instructions for determining the capacity of the hard drive of the Apple MacBook laptop provided through the E-Warrior Digital Life and Learning Program. It also covers how to determine the size of folders on your laptop's hard drive. This is useful for routine monitoring purposes and when preparing for an exchange or re-image. It is intended for both students and employees.
Checking used and free space on your hard drive
Every hard drive has a maximum storage capacity. As you install programs and save files, the drive fills up. To check the maximum capacity, how much space you have used, and how much space you have left, do the following:
- Control-click the hard drive icon labeled MacBook Pro ## (e.g., MackBook 12) on your desktop and select Get Info
- Listed in the box under the General heading will be the capacity and available drive space (Fig 1)
Checking folder size
Basic steps
You can check the size of a single folder in two ways:
- Mouse-over the folder name. The tool tip will usually display the size of the folder. In Figure 3, I am checking the size of my Music folder via the tool tip. It's 2.64 GB.
- With the folder selected, right-click on it and select Properties. in Figure 4, I am checking the size of my Music folder via Properties. It's 2.64 GB.
Checking the size of your Home folder
You can use the two methods above to check the size of your entire Home folder, the one that probably holds all of your school-related and personal files.
- HP 8460w and 8470w: Your Home folder is located at Boot/Programs/Data (C:)\Users\[your username]
- HP 840 G1 and G2: Your Home folder is located at Windows (C:)\Users\[your username]
Important information about folder sizes
- If the folder size via properties is larger than the result via the tool tip, it's because you have hidden system-related subfolders. This will be evident when you check the size of your Home folder because it includes a large, hidden folder called AppData. Checking the size using properties includes hidden subfolders, whereas the tool tip does not. You do not want to back up hidden subfolders anyway, so your tool tip size will be more relevant. By default, you can't see hidden subfolders. You can unhide them if you wish.
- Sometimes, your tool tip will indicate that the folder size is larger than a certain amount. This means that the function that computes the size for the tool tip was not able to complete the task within the specified amount of time. If this happens, use properties to view the folder size.
