# The cache files 

--> located at  `%LocalAppData%\Microsoft\Windows\Explorer`

if you want to check their size before and after clearing—seeing them drop from hundreds of megabytes to near-zero confirms the operation worked.

```
Stop-Process -Name explorer -Force
Start-Sleep -Seconds 2
Remove-Item "$env:LOCALAPPDATA\Microsoft\Windows\Explorer\thumbcache_*.db" -Force
Start-Process explorer
```

 Removing the thumbnail cache deletes the corrupted entries. It also forces Windows to rebuild a clean version and fixes the flickering. There are two ways to delete the Windows thumbnail cache. The first is using Disk Cleanup. Follow these steps:
```
Search for cleanmgr and click the Disk Cleanup option.
Select the C drive or any drive letter that corresponds with your system drive and click OK.
Check Thumbnails in the Files to delete list.
Click OK, then click Delete files.
```
