In Disk Cleanup, should I delete Thumbnails?

Hi, Marcia,

Yes.

You're simply clearing and resetting the thumbnail cache which at times may be corrupted causing thumbnails not being properly displayed.

Hi Marcia

The correct way to run disk cleanup is explained below, you need to run it twice and yes, delete everything suggested by Disk Cleanup:

Open File Explorer

Click on your hard drive

On the Manage Tab, click Cleanup

Let Disk Cleanup do its initial scan

Select Everything in the list and choose Delete

Start Disk Cleanup again

Let Disk Cleanup do its initial scan

This time in the resulting dialog, click 'Cleanup System Files'

Let Disk Cleanup run another scan

Select Everything in the list and choose Delete

Hi,
Yes, you should. That's basically a cache of thumbnails of Images.
Refreshing aint a bad idea.

Hello,

Of course, you can. It is just cache of thumbnails not actual thumbnails. If thumbnails not displaying, usually we recommend to delete this thumbnail cache.

Regards.
