Extract text from CM0013 files
To convert your CM0013 file to another format, you need Clean Master or other Encoded software.
To convert other file formats to the "Encrypted Safe Box File" file type, you need software like Clean Master or a similar tool.
A .cm0013 file is a secured data container created by the "Safe Box" privacy feature within Clean Master, a system optimization tool for Android developed by Cheetah Mobile. These files act as digital vaults, encapsulating personal media - such as JPG photos and MP4 videos - behind a layer of encryption to hide them from the device's standard gallery and file browser.
While effective for privacy on a mobile device, .cm0013 files present significant challenges when transferred to a PC or when the original app is uninstalled. The main limitation is proprietary lock-in: the files are not standard images or videos and cannot be opened by common viewers like Microsoft Photos or VLC Media Player. Users often encounter these files after backing up data to a computer, only to realize the content is unreadable without the original decryption key managed by the Clean Master app. To access the content, the most reliable workflow is to restore the files using the original application, effectively "converting" them back to their native formats like PNG or AVI. For archiving or sharing, once decrypted, these files should be stored in universal standards like PDF or HEIC to avoid future access loss.
Convert.Guru analyzes your CM0013 file, detects the exact format, and lets you read the text inside.
Users also converted CM, MP4, ZIP, EXE, JPG, SRF, SSIF, BTN and CM0012 files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CM0013 converter.
