Large files can quickly consume available storage on a Windows computer. Videos, software installers, backups, downloads, and application data can take up several gigabytes without being noticed.
If your computer is running low on storage, finding the largest files can help you determine what is using the most space before deciding what to remove.
Windows provides several built-in ways to find large files on Windows, including File Explorer, Storage settings, and PowerShell.
Why Should You Find Large Files?
Finding large files is useful when:
- Your storage drive is nearly full.
- Windows displays a low disk space warning.
- You need to make room for an application.
- You want to clean up old downloads.
- You have accumulated large videos or archives.
- You are trying to identify what is consuming your storage.
Large files are not necessarily unnecessary files. Always check what a file contains and whether you still need it before deleting it.

Method 1: Find Large Files Using File Explorer
File Explorer is the simplest method for most users.
Step 1: Open File Explorer
Press:
Windows + E
Step 2: Select a Drive
Open This PC and choose the drive you want to search.
For example:
Local Disk (C:)
Step 3: Search for Large Files
Click the search box in the upper-right corner.
You can use Windows search filters to narrow down files by size.
For example, type:
size:giganticWindows can then display files that fall into its larger size category.
You can also search for specific file types when looking for large media or archive files.
For example:
*.mp4or:
*.zipThis can help you locate large videos, compressed archives, or other file types.
Method 2: Sort Files by Size
If you are already inside a folder containing many files, you can sort them by size.
Step 1: Open the Folder
Navigate to the folder you want to inspect.
Step 2: Change the View
Use the Details view if necessary.
Step 3: Sort by Size
Click the Size column.
The files will be sorted according to their size.
This method is particularly useful for folders such as:
- Downloads
- Videos
- Documents
- Desktop
It may not provide a complete picture of the entire drive because files are distributed across many folders.
Method 3: Use Windows Storage Settings
Windows Storage settings can help identify categories consuming significant amounts of space.
Step 1: Open Settings
Press:
Windows + I
Step 2: Open Storage
Go to:
System → Storage
Windows will display categories such as:
- Installed apps
- Temporary files
- Documents
- Pictures
- Videos
- Other
Step 3: Investigate Large Categories
Select a category to see more information where available.
For example, if Videos is consuming a large amount of storage, you can investigate your video folders for files that are no longer needed.
Storage settings are useful for understanding what type of data is consuming space, while File Explorer is better for locating individual large files.
Method 4: Find Large Files in the Downloads Folder
The Downloads folder is often a good place to look for files that are no longer needed.
Open:
File Explorer → Downloads
Then switch to Details view and sort by Size.
Look for:
- Large software installers
- ISO files
- Videos
- ZIP archives
- PDF collections
- Old downloaded files
Before deleting anything, make sure the file is no longer needed.
Software installers, for example, may be safely removable if the software is already installed and you do not need the installer again.
Method 5: Find Large Files Using PowerShell
PowerShell can be useful when you want to search for files above a specific size.
Open PowerShell and use an appropriate command to search a particular folder.
For example, to find files larger than 1 GB in a folder, you can use:
Get-ChildItem "C:\Users\YourName\Downloads" -File -Recurse -ErrorAction SilentlyContinue |
Where-Object {$_.Length -gt 1GB} |
Sort-Object Length -Descending |
Select-Object FullName, @{Name="SizeGB";Expression={[math]::Round($_.Length / 1GB, 2)}}Replace YourName with your Windows user-folder name.
The results can show the file path and approximate size.
PowerShell is more technical, but it gives you greater control over the search.
Method 6: Search for Specific Large File Types
Sometimes you already know what type of file is likely consuming your storage.
You can search for common large file types using File Explorer.
Videos
*.mp4*.mkvCompressed Files
*.zip*.rarDisk Images
*.isoInstallers
*.exeThese searches can help identify files that are commonly large.
However, do not delete files simply because their extension looks familiar. Verify what the file is used for first.
Where Are Large Files Commonly Found?
Large files can appear in many locations.
Common places to check include:
Downloads
Old installers, archives, videos, and downloaded files can accumulate here.
Videos
Video files can consume significant amounts of storage.
Pictures
High-resolution photographs and image collections can also become large.
Desktop
Files saved directly to the Desktop still consume space on your system drive.
Documents
Large project files, archives, and exported documents may occupy substantial space.
Application Data
Applications can store caches and other data that may become large over time.
Be especially careful with application and Windows system folders. Do not manually delete unfamiliar files from these locations.
How to Find the Largest Files Safely
Finding a large file does not mean that you should immediately delete it.
Before deleting a file, ask:
- What is the file?
- Do I still need it?
- Is it part of an installed application?
- Is it a personal file?
- Is there another copy or backup?
- Can it be moved to another storage location instead?
This is particularly important for files inside system and application folders.
If you are simply trying to recover storage space, Windows’ built-in cleanup options are often safer than manually deleting unfamiliar system files.
What Large Files Should You Delete?
Potential candidates for removal may include:
- Old downloads
- Duplicate personal files
- Unneeded videos
- Old ZIP archives
- Unused software installers
- Personal files you have already backed up
- Other files you no longer need
Avoid deleting:
- Windows system files
- Unknown files inside system folders
- Application files you do not recognize
- Files required by installed software
- Important personal data without a backup
When uncertain, leave the file alone until you understand its purpose.
How to Free Up Space After Finding Large Files
After identifying unnecessary large files, you can:
- Delete files you no longer need.
- Empty the Recycle Bin.
- Move personal files to another drive.
- Back up large files to appropriate cloud storage.
- Uninstall applications you no longer use.
- Remove unnecessary temporary files.
If your Windows drive continues to show low storage after cleanup, investigate other storage categories rather than repeatedly deleting individual files.

Large Files vs. Large Folders
A single large file is easy to identify, but sometimes storage is consumed by many smaller files inside one folder.
For example, a browser or application may have thousands of files that collectively use several gigabytes.
In this situation, finding one large file may not reveal the real source of the storage usage.
Use Windows Storage settings to identify the category consuming space, then investigate the appropriate folder or application.
How to Avoid Accidentally Deleting Important Files
Before deleting a large file:
Check the file name → Check its location → Determine what created it → Confirm whether you need it → Back it up if necessary → Delete only when certain.
Do not use file size alone as a reason for deletion.
A large file can be an important backup, project, database, or application component.
