What is a CM0013 file?
A .CM0013 file is an encrypted file from a vault. It is primarily created by Clean Master, a mobile optimization app developed by Cheetah Mobile. The app uses this format to hide and secure user photos and videos. Alternatively, a .CM0013 file can also be a Samsung Smart TV Index File created by a Samsung television on a connected USB storage device.
How to open CM0013 files?
Because a .CM0013 file is usually encrypted, you need the original Clean Master application to open and view the hidden media. If you no longer have the app, you will need a technical decryption tool. Developers often share decryption scripts on platforms like GitHub to restore these files back to standard image or video formats. If the file is a Samsung Smart TV Index File, the TV system reads it automatically. You do not need to open it manually on a computer.
