Secure File Shredder is a filesystem-level multi-pass file and directory shredder and mounted-folder free-space sanitizer for Linux desktops. An independent Linux alternative inspired by SDelete, it overwrites regular files in place before unlinking and scrubs unallocated space inside writable mounted folders using standard user-space file operations.

Key Features:

• Multi-Pass File & Directory Overwrite: Supports 1-Pass Zero (0x00), 3-Pass Overwrite (0x00, 0xFF, os.urandom with readback verification), and 7-Pass Shred patterns with explicit os.fsync() flushes after every pass.
• Metadata Scrubbing Before Unlink: Truncates overwritten files, performs multi-round random alphanumeric filename renames to scrub directory entry names, syncs parent directories, and unlinks targets cleanly.
• Bounded Mounted-Folder Free-Space Sanitizer: Inspects real mounted Linux filesystems via /proc/mounts and os.statvfs(), writing bounded zero/random wipe container files in any selected writable folder with automatic cleanup.
• Live Speed Meter & Wipe Audit Log: Measures real MB/s write throughput, supports Pause/Resume/Cancel, inspects file inodes and byte headers, and exports timestamped wipe audit logs to CSV, JSON, or TXT.
• Bilingual Interface: Instant switch between Vietnamese and English.
