BitFastCopier

Large file copies on a Mac, fast and verified.

BitFastCopier copies folders with hundreds of thousands of files between disks and volumes. On the same APFS disk the copy is instant thanks to cloning; between different disks every file is verified with a SHA-256 checksum.

macOS

What it does

Instant cloning

On APFS volumes files are cloned instead of rewritten: the copy is immediate and uses no extra space.

Integrity check

Between disks each file is read back and checked with a SHA-256 checksum.

Dry run

Simulates the whole copy without writing anything and shows in advance how many files will be cloned, transferred or skipped.

Adaptive queue

The number of parallel copies adjusts itself to how the disks are performing.

Conflict rules

Choose what happens to files already at the destination; macOS service files are excluded automatically.

Links handled

Aliases and symbolic links are copied correctly in every case.
