To find large files on Windows 11, start in Settings → System → Storage, then search your personal folders in File Explorer with size:>1GB and sort the results by size. Old recordings, installers, and archives are useful places to look. A large file is a candidate for review, not proof that it is safe to delete.
Prefer a shorter search? eclean's Cleaner includes a large file finder with size and modified date beside each result, so you can review the biggest candidates together. Download eclean for Windows.
1. Find the category using the space
Open Settings → System → Storage and wait for the categories to load. Check whether the space is mainly in installed apps, personal files, temporary files, or system storage. Choose Show more categories if you need the fuller breakdown.
Open Cleanup recommendations and review Large or unused files when that section is available. Treat it as a shortlist. An old project or rarely opened archive can still be important. Microsoft's Storage settings guide explains the categories and cleanup recommendations.
For another drive, look under Advanced storage settings → Storage used on other drives. If installed games account for most of the space, move or uninstall them through their launcher rather than deleting their largest data files by hand.
This first check saves time. A drive full of applications needs a different response from one full of screen recordings. For a complete cleanup order, use the full C drive guide.
2. Search personal folders in File Explorer
Press Windows + E and open a folder such as Downloads, Videos, or Documents. Click its search box, type size:>1GB, and press Enter. Windows searches within that location and its subfolders.
Start in one likely folder rather than searching every drive at once. Non-indexed locations can take longer, so wait for the search to finish before judging the results. These examples use English Windows search syntax. Localized installations may use translated property names.
size:>500MBfinds a broader set of large files.size:>5GBnarrows the hunt to the biggest candidates.*.zip size:>500MBlooks for large ZIP archives.*.mp4 size:>1GBlooks for large MP4 videos.
Switch to View → Details, then click Size to put the largest files first. Check the location as well as the filename. Search results can contain similarly named files from different projects.
The Size column sorts files but does not calculate the total contents of every folder. To inspect a folder's total, right-click it, select Properties, and wait for Windows to count its contents. A folder can use many gigabytes even when none of its individual files crosses your search threshold.
3. Get a ranked list with PowerShell
If you want full paths in one list, open PowerShell from Start. The following command lists the 25 largest files inside your Videos folder. It reads file metadata and does not delete anything.
$scanFolder = [Environment]::GetFolderPath('MyVideos')
if ([string]::IsNullOrWhiteSpace($scanFolder)) {
throw 'Choose a folder path before running this scan.'
}
Get-ChildItem -LiteralPath $scanFolder -File -Recurse -ErrorAction Continue |
Sort-Object Length -Descending |
Select-Object -First 25 FullName,
@{Name='SizeGiB'; Expression={[math]::Round($_.Length / 1GB, 2)}},
LastWriteTime |
Format-List
To inspect another folder, replace the first line with a path you recognize, such as $scanFolder = 'D:\Recordings'. The list is sorted by actual byte length before rounding, and SizeGiB displays binary gigabytes. LastWriteTime is the last modified time, not proof of when you last needed the file.
The command includes subfolders, leaves hidden files out by default, and reports access errors while continuing where it can. Its results are not a complete inventory of protected system storage. There is no need to run as administrator or take ownership of Windows folders for this task.
On a large folder tree, collecting and sorting the list can take time. Start with a narrow location. The command checks file sizes without hashing or deliberately opening file contents.
4. Check what a large result actually contains
A filename and a size are not enough to decide what goes. Look at the full path, the application that owns it, and whether you have another verified copy.
Good candidates for review include downloaded installers for software already installed, old exported videos, obsolete disk images, and archives whose contents you have already extracted and checked. An original recording or the only backup of a project deserves a different decision.
Leave pagefile.sys, hiberfil.sys, and files inside Windows servicing folders alone. Avoid manually removing large files from Program Files, Windows, or an application's data folder. Use the app's storage controls, its uninstaller, or Windows cleanup settings instead. The temporary files guide covers that route.
If two files appear to be duplicates, matching names and sizes are only clues. The duplicate files guide explains how to confirm matching contents before choosing a copy to remove.
5. Separate cloud file size from local disk use
A OneDrive file can appear huge in Explorer while its contents are stored online. Check its status icon and Properties → Size on disk before assuming deleting it will recover that much local space.
For a synced file you want to keep online, right-click it and choose Free up space when available. Confirm sync has finished first and remember that an online-only file needs an internet connection to open.
Deleting a file inside OneDrive can delete it from the cloud and other synced devices too. Microsoft's Files On-Demand guidance distinguishes removing a local download from deleting the file itself. Other sync tools have their own controls. Check them before treating a synced folder like a spare local copy.
6. Move or delete, then check the result
For files you need but rarely use, copy them to another drive and open the destination copies to verify them before removing the originals. Moving a file between two folders on the same drive does not free space on that drive.
For files you no longer need, use normal Delete and read any confirmation. Files that enter the Recycle Bin still occupy space until it is emptied. Large files and some storage locations can bypass the bin, so do not assume every deletion has an undo.
Review the Recycle Bin before emptying it, then return to This PC or Storage settings to check free space. If the recovered amount is smaller than expected, check for files still in the bin and cloud placeholders that used little local storage.
Keep the biggest candidates visible
You do not need to inspect every small file to recover meaningful space. Start with the largest personal files, verify what they are, and use the owning app's controls for software and system data.
eclean's Cleaner brings large-file candidates together with their size and modified date for review. It also covers everyday clutter when the problem is thousands of small caches rather than a few large downloads. Download eclean free.
