Extract text from Locked media files (LOCK)
To convert LOCK Locked files to another format, you need Android Vaults and Package Managers or other System software.
To convert other file formats to the "System Lock File" file type, you need software like Android Vaults and Package Managers or a similar tool.
A .lock file is an extension used for several completely different purposes: disguised media files from Android vault applications, plain-text dependency trackers for software projects, system access control flags, or files maliciously encrypted by ransomware. Programs like Composer or npm use lock files to freeze software versions, while databases like MongoDB use them to prevent conflicting data writes.
The main disadvantage of a .lock file is its extreme ambiguity. Users often encounter these files when an Android privacy app hides a JPG or MP4 by renaming it, making the media inaccessible in standard galleries. Conversely, if your personal documents suddenly change to .lock, you have likely been hit by malware (like Locky ransomware). Standard converters cannot fix mathematically encrypted ransomware files; they require dedicated decryption keys. However, for package manager files, the format is often raw JSON, which is dense and difficult for non-developers to read.
For Android vault files, convert them back to JPG or MP4 to restore standard media viewing. For dependency tracking files, convert them to JSON or TXT to make them readable. We will safely inspect the file's header to determine its true underlying format and provide the correct conversion path.
Convert.Guru analyzes your LOCK file, detects the exact format, and lets you read the text inside.
Users also converted RBXL, FILELOCK, KCB, REALM, LOCKED, MX, MPH, RBXM, LDB, PDF, MANIFEST-000001, LCK and KPF files.
If you want to convert LOCK file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, PID or SOCK, you can use Android Vaults and Package Managers or similar software from the "Access Control and Encrypted Media" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to LOCK, try Android Vaults and Package Managers or another comparable tool in the "Access Control and Encrypted Media" category.
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 LOCK converter.
