Thumbnails on Android devices can quickly accumulate and take up valuable storage space. To delete thumbnails on an Android phone, navigate to the DCIM folder using a file manager app and remove the .thumbnails folder. This simple process can free up significant storage and improve device performance.
Many Android users are unaware of the hidden .thumbnails folder that stores small preview images of photos and videos. Over time this folder can grow quite large. Removing these unnecessary files can be a quick way to reclaim storage space on your device without deleting any of your actual photos or videos.
Deleting thumbnails is a safe and reversible process. Android will regenerate thumbnails as needed when you view photos or videos again. For users who want to prevent thumbnails from being created in the future there are also methods to block the .thumbnails folder from being recreated after deletion.
Managing Thumbnails on Your Android
Thumbnails are small image previews that help you quickly identify files on your Android phone. While they’re helpful, they can also take up storage space and sometimes show previews of images you’d rather not see at a glance. Here’s how to delete thumbnails on your Android phone and manage them effectively:
Understanding Thumbnails
Thumbnails are automatically generated by your Android system when you take pictures, download images, or receive videos. They are stored in a hidden folder on your device. Deleting thumbnails won’t delete the original files, but it will remove the preview images.
Methods to Delete Thumbnails
There are a few ways to delete thumbnails on your Android phone:
- Manually Deleting from File Manager:
- Open your phone’s File Manager app.
- Look for a folder named DCIM or Pictures. This is where most image thumbnails are stored.
- You might find a hidden folder named .thumbnails. If you see it, open it and delete the files inside. Note that hidden folders may not be visible by default in some file managers. You may need to enable “Show hidden files” in the file manager settings.
- Using a Cleaning App:
- Download a reputable cleaning app from the Google Play Store. Some popular options include Files by Google, CCleaner, or Norton Clean.
- Open the app and look for an option to clean junk files or clear cache.
- Run the cleaning process. The app will identify and delete thumbnail files, along with other unnecessary files, freeing up storage space.
- Clearing Gallery App Data:
- Go to Settings > Apps > See all apps.
- Find your Gallery app in the list and tap on it.
- Tap on Storage & cache.
- Tap on Clear cache or Clear data. This will remove thumbnails generated by the Gallery app.
Important Considerations
- Hidden Files: As mentioned, the
.thumbnailsfolder might be hidden. You may need to adjust your file manager settings to see it. - Storage Space: Deleting thumbnails can free up a small amount of storage space. However, it’s not a significant amount unless you have a large number of images and videos.
- Regeneration: Your phone will automatically regenerate thumbnails as you view images and videos again.
Thumbnail Management Tips
- Regular Cleaning: Use a cleaning app periodically to delete unnecessary files, including thumbnails.
- Cloud Storage: Consider storing your photos and videos in cloud storage services like Google Photos or Dropbox. This can free up space on your device and reduce the need for thumbnails.
- Gallery App Settings: Some gallery apps have settings that allow you to control thumbnail generation or limit their size.

Understanding Thumbnails on Android
Thumbnails play a key role in Android devices. They help users quickly view and navigate their media files. These small image previews impact device storage and performance.
The Role and Function of Thumbnails
Thumbnails are small preview images of photos and videos on Android devices. The gallery app creates these miniature versions to speed up browsing. They let users see their media without loading full-sized files.
Thumbnails make scrolling through photos and videos smoother. Apps like QuickPic use them to show media grids faster. When you tap a thumbnail it opens the full image or video.
Android stores thumbnails in a hidden .thumbnails folder. This folder is usually in the DCIM directory. The system updates thumbnails when you add or change media files.
Storage Impact of Thumbnails
Thumbnails can take up a lot of space over time. The .thumbnails folder grows as you add more photos and videos. This can cause storage issues on devices with limited space.
Large thumbnail folders may slow down your device. They can make the gallery app take longer to load. Clearing thumbnails can free up storage and improve performance.
To manage thumbnail storage:
- Use a file manager to find the .thumbnails folder
- Delete old thumbnails you don’t need
- Use apps that don’t create extra thumbnails
- Clear app cache to remove temporary thumbnail files
Some users create a dummy file to stop thumbnail creation. This can save space but might affect how some apps work.
