The mobile phone downloaded the video online and deleted it after watching it. I can't see the name in the folder, but the size of the video still occupies the memory under the folder.
Complete deletion method:
1. Download and install Cheetah Cleanup Master Extreme Edition.
2. Open the system slimming function of the software to scan large files.
3. Select the file to delete and delete it.
4. After deletion, click Cheetah Cleaner to clean with one click, and the system garbage will be cleaned with one click.
