Windows 11 Can Now Display File Sizes in MB/GB! How to Enable and Configure It in File Explorer
Explains a new change in Windows 11 that allows File Explorer to automatically display file sizes in KB, MB, or GB units, along with how to check for updates and configure the Size column for easier and faster management of space and large files.
Have you ever been frustrated when opening File Explorer in Windows 11 and seeing large files displayed as millions of kilobytes (KB), making it difficult to estimate their actual size? This article from SyncTech Solution will explain a new change that helps you see file sizes immediately in megabytes (MB) or gigabytes (GB), along with how to configure your File Explorer for more convenient use.
Understand Before Fixing
Normally, in previous Windows versions, and even in early Windows 11, when we viewed files in Details mode, the "Size" column always displayed all file sizes in KB. For small document files, this might not be an issue, but when managing large files, such as a 10 GB video file, the system would display a long number like 10,485,760 KB, which is difficult to read and compare.
Recently, Microsoft has gradually rolled out an update specifically addressing this. File Explorer will now be smarter and automatically choose the appropriate unit for file sizes, for example:
- Files smaller than 1 MB will still display as KB.
- Larger files will display as MB.
- Very large files will display as GB.
This change does not force display to always be in GB, but rather adjusts the units to match the actual size, making it much easier to read and manage files. This feature comes with Windows updates, so the best way to utilize it is to always keep your system updated to the latest version.
Before You Begin
This setting only adjusts the view in File Explorer and does not directly interact with data files, so the risk is very low. However, to ensure a smooth system update (if necessary), please prepare as follows:
- Save all pending work: Installing Windows Updates sometimes requires a system restart.
- Check your internet connection: Ensure a stable connection to download updates.
How to Safely Do It
Follow these steps to check if you have received this new feature and configure it for proper display.
1. Check for and Install Latest Windows Update
WHAT: Update the Windows 11 operating system to the latest version.
WHERE/HOW: Go to Start > Settings (gear icon) > Windows Update, then click the "Check for updates" button.
WHY: This automatic unit-adjusting file size display feature is released with Windows Updates. Keeping your system up-to-date is therefore the correct and safest way to receive new features, as well as security and performance improvements.
EXPECTED RESULT: If new updates are available, the system will automatically begin downloading and installing them. Upon completion, you may be prompted to restart your computer.
2. Restart Windows Explorer (Optional)
WHAT: Instruct the Windows Explorer program to restart, so changes take effect immediately without restarting the entire system.
WHERE/HOW: Press Ctrl + Shift + Esc to open Task Manager. Look for "Windows Explorer" in the Processes tab, right-click it, and select "Restart".
WHY: Sometimes after an update, minor changes might not immediately appear. Restarting only Explorer is a quick way to load new settings.
EXPECTED RESULT: The screen will flicker slightly. The Taskbar and open windows will briefly disappear and then reappear.
3. Set View to Details
WHAT: Change the file display style in the folder to a list with details.
WHERE/HOW: Open File Explorer. Go to the top menu, click "View", then in the Layout section, select "Details".
WHY: The "Size" column only appears in Details view. If you are using Icons or List view, you will not see file sizes as numbers.
EXPECTED RESULT: Files and folders will be arranged as a list, with various data columns such as Name, Date modified, Type, and Size.
4. Enable "Size" Column
WHAT: Ensure that the column for displaying file size is enabled.
WHERE/HOW: In Details view, right-click the table header area (e.g., where "Name" or "Date modified" is located). A sub-menu will appear. Check if there is a tick mark next to "Size". If not, click to enable it.
WHY: Sometimes users may accidentally disable the Size column, preventing file size information from being displayed. This setting will restore the column's visibility.
EXPECTED RESULT: The "Size" column will appear in the file list table.
5. Auto-Adjust Column Width
WHAT: Adjust the column width to fit the displayed data.
WHERE/HOW: Move your mouse cursor to the dividing line between the "Size" column header and the next column to the right, until the cursor changes to a double-headed arrow. Then, double-click.
WHY: To ensure that unit names (KB, MB, GB) are not hidden or truncated, allowing full visibility of file size information.
EXPECTED RESULT: The width of the "Size" column will automatically adjust to fit the longest item within it.
Verify Results
After following all steps, try opening File Explorer to a folder containing various file sizes, such as the Downloads folder or a folder storing images and videos.
- Observe the "Size" column: You should see small document files displayed in KB, image or music files in MB, and large video or program installation files in GB.
- Compare files: Try to find a file whose approximate size you know, for example, a 2 GB installation file. You should see a number close to "2 GB" instead of "2,097,152 KB" as before.
If It Still Doesn't Work
If you have updated Windows to the latest version but still see all file sizes in KB, it's possible that this feature has not yet been rolled out to your machine (Gradual Rollout), which is normal for Microsoft. We recommend waiting for the next update cycle.
This is not a system error, but rather a feature enhancement that takes time to propagate. However, if your File Explorer is experiencing other issues such as slow performance, freezing, or frequent crashes, the problem is likely due to another cause and should be checked by IT or a specialist for a targeted solution.
The ability of File Explorer in Windows 11 to display file sizes in appropriate units (KB/MB/GB) is a small but significant improvement that greatly enhances the user experience. It allows for faster and more intuitive management of storage space and files. By keeping Windows updated, you will automatically receive useful features like this.
