LRGEX-Compress

Extremely fast. No waiting. LRGEX Compress is built around Zstandard (zstd) — a modern compression algorithm optimized for speed. It uses all your CPU cores automatically, so big folders finish in seconds instead of minutes.

For everyday backups and file sharing, seconds matter more than a slightly smaller archive.

Features ? Zstandard compression — uses all CPU cores automatically ? Windows Explorer integration — right-click any file or folder ? Progress window with live speed and ETA ? Atomic archive creation — interrupted compress never leaves a broken file ? ZIP extraction ? RAR extraction ? Empty folder preservation ? Ed25519 cryptographically signed auto-updates ? MIT License ? No administrator required ? Command-line support

What makes it different Atomic writes. If your PC crashes or loses power mid-compress, you never get a broken half-written archive. The file only appears when it's 100% complete. Empty folders preserved. Some archivers drop empty directories silently. LRGEX Compress keeps your exact folder structure. Metadata preserved exactly. File contents, modification/creation timestamps (whole-second precision), Windows attributes (hidden, read-only, system), and symbolic links all round-trip identically. NTFS alternate data streams are not supported (rarely used; not planned). Cancel is clean. Click Cancel, the partial archive is deleted. No orphaned files. Signed auto-updates. Every update is cryptographically verified using Ed25519 before installation. Per-user install. No admin prompt. No UAC. Works on locked-down corporate machines.
