Published August 23, 2026 File Explorer search ``` size:>1GB ``` Type that into the File Explorer search box, from *This PC* so all drives are searched. Details below, plus a PowerShell scan that covers folders the index skips. ## The built-in way: File Explorer search Open File Explorer and click **This PC** in the left sidebar so the search covers every drive, then type `size:>1GB` in the search box and press Enter. Windows lists every indexed file over 1 GB. 1. Open File Explorer and click **This PC**. 2. Click the search box at the top right — it works in any folder, but *This PC* searches all drives. 3. Type `size:>1GB` and press Enter. 4. Right-click the **Size** column header and choose *Sort descending* to put the biggest files at the top (switch to Details view if you do not see the Size column). The syntax also supports ranges: `size:1GB..2GB` finds files between 1 and 2 GB, `size:>500MB` finds everything larger than 500 MB, and `size: PowerShell ``` Get-ChildItem C:\ -Recurse -File -ErrorAction SilentlyContinue | Sort-Object Length -Descending | Select-Object -First 20 FullName, @{n="SizeGB";e={[math]::Round($_.Length/1GB,2)}} ``` Recursing over a whole drive with [Get-ChildItem](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.management/get-childitem) is slow — expect several minutes on a busy `C:`. Scope the scan to where big files usually live and it finishes in seconds: PowerShell ``` Get-ChildItem C:\Users -Recurse -File -ErrorAction SilentlyContinue | Sort-Object Length -Descending | Select-Object -First 20 FullName, @{n="SizeMB";e={[math]::Round($_.Length/1MB,1)}} ``` Point the path at `C:Users`, `C:WindowsTemp` or your Downloads folder. `-ErrorAction SilentlyContinue` skips folders you cannot read instead of aborting the scan; add `-Force` to include hidden files such as `hiberfil.sys` and `pagefile.sys`. Raise `-First 20` to `-First 50` for a deeper list. ## Where big files hide - **Downloads** — installers, ISOs and old backups collect quietly for years. - **AppData\Local\Temp** — application and update caches routinely reach gigabytes. - **Windows.old** — the previous Windows installation, kept for rollback; a full copy is easily tens of gigabytes. It never shrinks itself — remove it via Settings → System → Storage → Temporary files → *Previous version of Windows*. - **hiberfil.sys and pagefile.sys** — hidden, system-protected files roughly the size of your RAM. They look alarming in a scan, are locked by Windows, and are safe to leave alone. ## Safe cleanup (built-in only) When space is tight, remove what Windows itself already offers to clean. Nothing here needs a third-party "disk cleaner": - **Temporary files:** Settings → System → Storage → Temporary files, tick the categories you want, then Remove files. - **Recycle Bin:** right-click it and choose *Empty Recycle Bin*. - **Windows Update cache:** stop the service, clear the download cache, restart it — Windows rebuilds it automatically: PowerShell ``` Stop-Service wuauserv Remove-Item C:\Windows\SoftwareDistribution\Download\* -Recurse -Force Start-Service wuauserv ``` Run those three lines from an elevated PowerShell — [Remove-Item](https://learn.microsoft.com/en-us/powershell/module/microsoft.powershell.management/remove-item) accepts wildcards, so the update cache empties in a single pass. If a specific update is stuck broken instead, remove it with `wusa /uninstall /kb:KBxxxxxxx` — replace the number with the affected update's KB. Before deleting anything, confirm which drive is actually low with the [PowerShell disk space check](https://itinsighthub.com/guides/powershell-get-disk-space/). ## FAQ **Is there a built-in disk usage analyzer?** Partly. Settings → System → Storage shows usage per category (apps, temporary files, media and so on) and can clean them. For a per-file ranking, the File Explorer size: search covers indexed folders and the PowerShell scan above covers everything else. There is no built-in equivalent of third-party folder-map tools. **Why is my search missing system files?** File Explorer search reads the Windows index, which covers user folders like Downloads and Documents but not most of C:\Windows or other system locations. If a file does not show up, run the same size: query from inside that specific folder, or use the PowerShell scan, which does not depend on the index at all. **Is it safe to delete hiberfil.sys?** Do not delete the file directly — Windows keeps it locked. To disable hibernation and let Windows remove it, run powercfg /h off from an elevated PowerShell and restart. Re-enable hibernation anytime with powercfg /h on. **Does Windows 11 show folder sizes natively?** Not a breakdown. Right-click a folder and choose Properties to see the total size of everything inside it, but Explorer cannot rank the largest subfolders the way it ranks files. A scoped PowerShell scan is the native workaround. ## More IT tools Explore the networking references and calculators: - [PowerShell: get disk space](https://itinsighthub.com/guides/powershell-get-disk-space/) — check free space locally and on remote servers. - [PowerShell: list installed software](https://itinsighthub.com/guides/powershell-list-installed-software/) — registry inventory for audits. - [IPv4 subnet calculator](https://itinsighthub.com/subnet-calculator/) — network, broadcast and host range for any CIDR block. - [Subnet cheat sheet](https://itinsighthub.com/subnet-cheat-sheet/) — printable mask table from /0 to /32. --- © 2026 ITInsightHub · [About](https://itinsighthub.com/about/) · [Contact](https://itinsighthub.com/contact/) · [Privacy](https://itinsighthub.com/privacy/)
