Multi-destination file copy with checksum verification — built for photographers and DITs who demand bulletproof file transfers and verifiable reports.
Designed for photographers and DITs — fast to set up, bulletproof in use, verifiable by anyone.
Copy your card to two or three drives at once, in parallel — one read pass, multiple safe destinations.
xxHash64, MD5, or SHA256 — hashes computed while copying, then re-verified from disk to prove every file matches.
Atomic partial-file writes, OS-level fsync, and cache-bypass verification — no half-written files, no false positives.
Professional per-destination reports with file table, hashes, speed graph, and tamper-evident integrity hash.
Industry-standard Media Hash List — compatible with ShotPut Pro, Silverstack, DaVinci Resolve and more.
Filename collision detected? Pick Skip / Overwrite / Keep both per file — never lose a shot to a silent skip.
Optional second pass re-hashes source files to detect bit-rot during the copy — catches even the rarest read errors.
Disk space, write permissions, source readability — checked before the job starts, not halfway through.
Per-destination progress bars, MB/s + ETA, menu bar mini progress and Dock badge while you work.
