<\/a>Show Folder Size From Properties<\/p><\/div>\n
Advantages<\/h3>\n
- \n
- Simple and Quick<\/strong>: Only takes a few clicks.<\/li>\n
- Detailed Information<\/strong>: Also shows location, creation date, and attributes.<\/li>\n
- No Third-Party Software Required<\/strong>: Fully built into Windows.<\/li>\n<\/ul>\n
Disadvantages<\/h3>\n
- \n
- One Folder at a Time<\/strong>: There’s no way to compare or sort multiple folders at once.<\/li>\n
- Manual Process<\/strong>: Checking many folders means repeating the same steps over and over.<\/li>\n
- Limited Compatibility<\/strong>: Sizes can be inaccurate for some network or cloud-synced folders.<\/li>\n<\/ul>\n
Display Folder Sizes in the Windows 11 Size Column<\/h2>\n
By design, File Explorer’s Size column only shows sizes for individual files – folders are left blank. This is intentional: calculating a folder’s size means recursively scanning every file inside it, including nested subfolders, which would slow down browsing on large drives if done automatically every time you open a window.<\/p>\n
Windows itself has no setting to turn this on. Some third-party customization tools, such as Windhawk<\/strong>, offer community mods that force folder sizes into the Size column – but this comes at a real cost. To make this work, Windhawk installs a background service that runs continuously and injects code directly into
explorer.exe<\/code> every time it starts, so it can intercept and modify how File Explorer behaves. That means a process running at all times in the background, even when you’re not checking folder sizes, plus the general risk that comes with injecting third-party code into a core Windows process – instability, conflicts with future Windows updates, or slower Explorer performance overall.<\/p>\nWe’d recommend against this approach.<\/strong> A dedicated, standalone application like Folder Size gives you the same information – and far more of it – without installing anything that hooks into Explorer or runs in the background. See Show All Folder Sizes at Once Using a Free Disk Analysis App<\/a> below for a safer way to get this.<\/p>\n
Why This Approach Is Risky<\/h3>\n
- \n
- Always-On Background Service<\/strong>: Runs continuously, using system resources whether or not you’re actively checking folder sizes.<\/li>\n
- Injects Into a Core Windows Process<\/strong>: Modifying
explorer.exe<\/code> directly can cause instability, crashes, or conflicts with Windows updates.<\/li>\n- No Vendor Accountability<\/strong>: Mods are community-submitted, so quality and security vary between individual submissions.<\/li>\n<\/ul>\n
A Safer Alternative<\/h3>\n
- \n
- No Background Service<\/strong>: A dedicated app like Folder Size only uses resources while it’s actually open and running.<\/li>\n
- No System Hooks<\/strong>: Works alongside Windows Explorer rather than modifying it, so there’s no risk to Explorer’s stability.<\/li>\n
- More Information, Not Less<\/strong>: Shows every folder’s size in a sortable list, with charts and largest-folder reports – well beyond what a single Size column could show anyway.<\/li>\n<\/ul>\n
Show Folder Size From the Command Line<\/h2>\n
Using Command Prompt to check folder size is a flexible option for anyone who prefers a command-line interface or wants to script the process.<\/p>\n
- \n
- Open Command Prompt<\/strong>: Press Windows key + R<\/mark>, type “cmd,” and press Enter – or search for “Command Prompt” in the Start menu.<\/li>\n
- Navigate to the directory<\/strong>: Use cd<\/mark> followed by the folder’s path, for example
cd C:\\Users\\YourUsername\\Documents<\/code>. Replace “YourUsername” with your actual username.<\/li>\n- Run the size command<\/strong>: Type
dir \/s FolderName<\/code>, replacing “FolderName” with the folder you want to check.<\/li>\n- Read the result<\/strong>: Command Prompt lists every file and subdirectory inside the folder along with their sizes, then shows the total size of the folder and its contents at the end of the output.<\/li>\n<\/ol>\n
Example<\/h3>\n
To check the size of a “Photos” folder inside “Pictures”:<\/p>\n
- \n
- Open Command Prompt.<\/li>\n
- Navigate to Pictures:
cd C:\\Users\\YourUsername\\Pictures<\/code><\/li>\n- Run:
dir \/s Photos<\/code><\/li>\n<\/ol>\nCommand Prompt will list every file and subfolder inside “Photos” along with their sizes, then display the folder’s total size.<\/p>\n
Advantages<\/h3>\n
- \n
- Powerful and Scriptable<\/strong>: Can be automated or built into larger scripts.<\/li>\n
- Quick for Command-Line Users<\/strong>: No need to open a GUI or install anything extra.<\/li>\n
- Detailed Information<\/strong>: Also lists modification dates and file attributes.<\/li>\n<\/ul>\n
Disadvantages<\/h3>\n
- \n
- Learning Curve<\/strong>: Not intuitive if you’re unfamiliar with command-line syntax.<\/li>\n
- No Visual Breakdown<\/strong>: Just text output, no charts or sortable columns.<\/li>\n
- Risk of Mistakes<\/strong>: Easy to mistype a path or command if you’re not careful.<\/li>\n<\/ul>\n
Display Folder Sizes Using PowerShell<\/h2>\n
PowerShell offers a more flexible, scriptable way to check folder sizes than Command Prompt, especially for bulk operations.<\/p>\n
- \n
- Open PowerShell<\/strong>: Press Windows key + X<\/mark> and select “Windows PowerShell,” or search for it in the Start menu.<\/li>\n
- Navigate to the directory<\/strong>: Use cd<\/mark> followed by the folder’s path, e.g.
cd C:\\Users\\YourUsername\\Documents<\/code>.<\/li>\n- Run Get-ChildItem<\/strong>: Type
Get-ChildItem -Directory -Recurse | Measure-Object -Property Length -Sum<\/code>.<\/li>\n- Read the result<\/strong>: PowerShell returns the total size in bytes, which you can reformat into KB, MB, or GB as needed.<\/li>\n<\/ol>\n
Example<\/h3>\n
To check the size of a “Photos” folder inside “Pictures”:<\/p>\n
- \n
- Open PowerShell.<\/li>\n
- Navigate to Pictures:
cd C:\\Users\\YourUsername\\Pictures<\/code><\/li>\n- Run:
Get-ChildItem -Directory -Recurse | Measure-Object -Property Length -Sum<\/code><\/li>\n<\/ol>\nAdvantages<\/h3>\n
- \n
- Scripting Capabilities<\/strong>: Ideal for automating repeated checks or bulk operations.<\/li>\n
- Tightly Integrated with Windows<\/strong>: Works consistently across modern Windows versions.<\/li>\n
- Customizable Output<\/strong>: Format results however you prefer.<\/li>\n<\/ul>\n
Disadvantages<\/h3>\n
- \n
- Learning Curve<\/strong>: Cmdlet syntax takes some getting used to.<\/li>\n
- Potential for Mistakes<\/strong>: Scripting mistakes can affect files if you’re not careful.<\/li>\n
- Less Intuitive Than a GUI<\/strong>: Slower to use for a single one-off check.<\/li>\n<\/ul>\n
Show All Folder Sizes at Once Using a Free Disk Analysis App<\/h2>\n
All the built-in methods above have the same limitation: they show you one folder at a time. To see every folder size in a drive at once, sorted and ready to act on, you need a dedicated disk space analyzer. Free options include Folder Size<\/strong>, TreeSize Free<\/strong>, and WinDirStat<\/strong> – all let you scan a full drive and view folder sizes in a sortable list rather than checking folders one by one.<\/p>\n
Find the largest files and largest folders<\/a>, sort folders and files by size, delete large unused files and folders to free up disk space, and visualize disk usage with pie or bar charts to spot space hogs at a glance. You can also print folder lists<\/a> or print a folder tree<\/a> for reporting or auditing.<\/p>\n

\nDownload Folder Size<\/a><\/p>\n
Compatible with Windows 11\/10\/8.1\/8\/7\/Vista (Both 32 & 64 Bit)<\/div>\n<\/div>\nFolder Size: Copy, Cut, Paste, Delete, and Rename<\/h3>\n
Beyond just showing sizes, Folder Size lets you Copy, Cut, Paste, Delete, and Rename files and folders directly from its results – including copying between Folder Size and Windows Explorer. Combined with the full Windows Explorer shell context menu built into the app, it functions as a Windows Explorer with folder sizes built in<\/a>.<\/p>\n
Automatic Updates – No Rescanning Required<\/h3>\n
Folder Size monitors file system changes and updates scan results automatically. If you copy, move, rename, or delete files in Windows Explorer, those changes reflect in Folder Size immediately, with zero added load on system performance – it uses native Windows change notifications rather than installing a background service or shell hook, so it has no impact on your PC when you’re not using it.<\/p>\n
Conclusion<\/h2>\n
Each of these methods works, and which one to use mostly comes down to how much detail you need. For a quick one-off check, folder tooltips or Properties are enough. For scripting or automation, Command Prompt and PowerShell get the job done. If you regularly need to see every folder size on a drive at a glance, sorted and ready to clean up, a dedicated tool like Folder Size<\/a> – free to download for Windows 11, 10, 8.1, 8, 7, and Vista – saves the most time.<\/p>\n
Show Folder Size Windows FAQ<\/h2>\n
\nHow can I view the size of a folder in Windows File Explorer?<\/h3>\n
Right-click the folder, select “Properties,” and check the “General” tab<\/strong> – the folder’s total size, including its contents, is displayed there.<\/div>\n<\/div>\n\nIs there a way to see folder sizes without opening Properties?<\/h3>\n
Yes – enable folder size tooltips in File Explorer’s View Options, then hover over any folder<\/strong> to see its size appear after a short delay.<\/div>\n<\/div>\n\nDoes Windows 11 show folder sizes in the Size column?<\/h3>\n
Not natively, and we’d avoid the workarounds that force it.<\/strong> Windows leaves the Size column blank by design. Tools like Windhawk can fake this by installing a background service that injects into explorer.exe, but that means a process running constantly and a real risk of instability. A standalone app like Folder Size shows the same information more safely, without touching Explorer at all.<\/div>\n<\/div>\n\nCan I use Command Prompt to check the size of a folder?<\/h3>\n
Yes – open Command Prompt, navigate to the folder’s directory with “cd,” then run “dir \/s FolderName.”<\/strong> The total size of the folder and its contents appears at the end of the output.<\/div>\n<\/div>\n\nIs PowerShell another option for displaying folder sizes?<\/h3>\n
Yes – navigate to the folder’s directory in PowerShell and run “Get-ChildItem -Directory -Recurse | Measure-Object -Property Length -Sum”<\/strong> to get the folder’s total size in bytes.<\/div>\n<\/div>\n\nWhat’s the fastest way to see every folder size on a drive at once?<\/h3>\n
A dedicated disk space analyzer like Folder Size, TreeSize Free, or WinDirStat<\/strong> – each scans a full drive and lists every folder’s size in a sortable table, which none of Windows’ built-in methods can do on their own.<\/div>\n<\/div>\n\nWhy doesn’t Windows show folder sizes by default?<\/h3>\n
Performance.<\/strong> Calculating a folder’s size means recursively scanning every file and subfolder inside it, which would slow down browsing on large or slow drives if Windows did it automatically every time a folder is displayed.<\/div>\n<\/div>\n\nAre there any third-party applications for showing folder sizes in Windows?<\/h3>\n
Yes – Folder Size, TreeSize Free, and WinDirStat are widely used free options<\/strong>, each offering sortable results, charts, or export features beyond what Windows provides natively.<\/div>\n<\/div>\nPlease share this article with your friends – they will thank you!<\/strong>
