fast-copy is now blitcp — new name, same tool ("blit" as in bit-block transfer, the block-order engine namesake). New home: https://blitcp.dev
Upgrading from fast-copy
Nothing breaks: run --update from v3.12.7 (or download fresh), and your existing dedup databases, transfer manifests, audit logs and saved connections are migrated in place on first run — nothing is re-hashed or restarted. The FAST_COPY_* environment variables remain honoured.
Highlights
- Interface in 7 languages (CLI + GUI): English, Ελληνικά, 中文, Deutsch, Italiano, Español, 日本語 —
--lang,BLITCP_LANG, or the GUI Settings. - Passphrase generator for credentials encryption:
blitcp creds encrypt --generate(and a Generate button in the GUI) — 6-word diceware, EFF wordlist, ~77 bits, fully offline. - Progress you can trust: the bar/ETA no longer jump to 100% with thousands of small files still copying; a failed verification now returns a proper exit code.
- Windows fixes: FAT32 path validation no longer blocks small files; the dedup DB placement handles unwritable drive roots (C:) gracefully.
- Release assets are now named
blitcp-*.
