TC File Locksmith - Find Processes Locking Files & Folders on Linux
TC File Locksmith is a native Linux desktop utility for inspecting open file descriptors, memory-mapped files, process working directories, and kernel file locks in real time.
An independent Linux alternative inspired by PowerToys File Locksmith for identifying which running processes hold open handles or locks on any file, folder, or mounted filesystem and safely unlocking them.
Key Features:
- Deep /proc Handle Scanner: Scans real /proc/[pid]/fd symlinks, /proc/[pid]/maps memory-mapped regions, /proc/[pid]/cwd working directories, and /proc/[pid]/exe binaries for any selected file or directory.
- Kernel File Lock Inspector: Reads real /proc/locks (FLOCK, POSIX, OFD) and /proc/[pid]/fdinfo descriptors, correlating device major:minor numbers and inodes with /proc/self/mountinfo and open process handles.
- Mountpoint Busy & Process Summary: Aggregates open handle counts per process and per mounted filesystem (with os.statvfs capacity telemetry) to diagnose busy directories and unmountable drives.
- Real Process Unlock Controls: Send real SIGTERM, SIGKILL, SIGSTOP, or SIGCONT signals via process-control with safety guards for PID 1 and the inspector process itself, plus a session audit log.
- Bilingual & Export Ready: Instant Vietnamese / English interface toggle and real CSV, JSON, and TXT report export.
