PowerShell Get Folder Size: Find It Now
When managing your computer’s storage or dealing with specific directories, it’s essential to know the size of a folder. PowerShell, a powerful automation and scripting language, can come to your rescue. In this article, we’ll explore how to use PowerShell to get the size of a folder, and we’ll provide you with useful scripts and tips to simplify the process.
PowerShell Basics
Before diving into folder size calculations, let’s cover some fundamental PowerShell concepts.
Get-ChildItem Cmdlet
Get-ChildItem is a versatile cmdlet in PowerShell that allows you to retrieve a list of items in a specified location. When used with the –Recurs parameter, it can traverse through subdirectories as well, making it perfect for our folder size calculations.
Measure-Object Cmdlet
Measure-Object is another handy cmdlet that, as the name suggests, measures various properties of objects. In our case, we’ll use it to calculate the size of folders by summing up the Length property of files within those folders.
Quick and Easy Folder Size Retrieval
The Quick and Dirty One-Liner
If you’re looking for a quick way to get the size of a folder in PowerShell, this one-liner is your go-to command:
| “{0} MB” -f ((Get-ChildItem C:\users\ -Recurse | Measure-Object -Property Length -Sum -ErrorAction Stop).Sum / 1MB) |
This command fetches the folder size of the C:\users directory in megabytes.
The Not-So-One-Liner
For those who prefer a more comprehensive script, we’ve created a PowerShell module that provides folder sizes in megabytes and gigabytes. You can find the module on GitHub.
To install it from the PowerShell Gallery, use the following command:
| Install-Module PSFolderSize |
For detailed instructions on how to run it, check the help documentation:
| Get-Help Get-FolderSize -Detailed |
The latest version, 1.7.0, offers features such as sorting the output by FolderName or SizeBytes and exporting the results as CSV, JSON, or XML files.
The Script in Action
Let’s take a closer look at how this script works in various scenarios:
Basic Usage
| .\Get-FolderSize.ps1 |
This command retrieves folder sizes for all folders in the default base path (C:\Users) and displays them in megabytes and gigabytes. Empty folders are omitted.
Specifying a Different Base Path
You can specify a different base path using the –BasePath parameter:
| .\Get-FolderSize.ps1 -BasePath ‘C:\Program Files’ |
This command fetches folder sizes for the ‘C:\Program Files’ directory.
Filtering by Folder Name
To retrieve the size of a specific folder within the base path, use the -FolderName parameter:
| .\Get-FolderSize.ps1 -BasePath ‘C:\Program Files’ -FolderName IIS |
This command specifically fetches the folder size of ‘IIS’ within ‘C:\Program Files’.
Copying and Using the Code
Feel free to copy and paste the provided PowerShell script and use it according to your needs. It’s a valuable tool for obtaining folder sizes efficiently.
Advanced Features
- Sorting by Size
You can sort the folder sizes by size, either in ascending or descending order. Here’s an example of sorting by size in descending order:
| $getFolderSize = .\Get-FolderSize.ps1 | Sort-Object ‘Size(Bytes)’ -Descending$getFolderSize |
This command sorts the folder sizes from largest to smallest.
- Omitting Specific Folders
The -OmitFolders parameter allows you to exclude specific folders from being included in the calculations. For example:
| .\Get-FolderSize.ps1 -OmitFolders ‘C:\Temp’,’C:\Windows’ |
This command excludes the ‘C:\Temp’ and ‘C:\Windows’ folders from the folder size calculations.
