What are Windows Thumb.db files? How do I find and delete Thumb.db files? Windows automatically creates a file known as Thumb.db for folders containing pictures or images. Thumb.db file caches thumbnails of all the images in the folder; this allows Windows to display the images quicker whenever the folder is opened.
The Thumb.db is a hidden file only viewable when the ‘Show Hidden Files’ option is turned on in the Folder Option settings. To prevent the Thumbs.db file from being created, follow these instructions:
- Open a folder, any folder in your Windows.
- Go to ‘Tools’ then select “Folder Options” as shown in the image below. (Step 1)
- Select the ‘View’ tab.
- Check the “Do not cache thumbnails” option as shown in the image below (Step 3)
- Click ‘OK’ to apply the changes
Do I Need Thumb.db?
It depends, if you use Windows Explorer to browse your photos, disabling it will cause the browsing experience to be sluggish as Windows will have to re-render the thumbnail everytime you open the folder.
