What Are Hidden Files on Your Phone?
Hidden files are files that are not visible in your normal file manager.
These files may include:
- App cache files
- Temporary system files
- Old deleted photos
- Hidden images or videos
- Background app data
- Secret folders
- Log files
Your phone hides these files to protect system settings. But sometimes these files remain even after deleting apps.
Over time, they:
- Take storage space
- Slow down your phone
- Reduce performance
- Create privacy risk

Why You Should Find Hidden Files
Many people ignore hidden files. But they can cause problems.
Here are the main reasons:
1. Free Up Storage Space
Hidden files can take 1GB to 10GB or more. If your phone says “Storage Full,” hidden files may be the reason.
2. Improve Phone Speed
Too many junk files slow down your device. Removing them makes your phone faster.
3. Protect Your Privacy
Sometimes apps store hidden copies of photos or documents. If you sell your phone without cleaning, someone can recover them.
4. Remove Virus or Malware Files
Some harmful apps hide files inside system folders.
