Byte Check: Media Management
Clone & Verify Cards & Drives
Only for Mac
$9.99
Mac
Back up camera cards and drives, then know for sure. Every file is read back and compared byte-for-byte with the original, so you can format the card with confidence.
Byte Check copies memory cards, external drives and folders, then proves the copy is perfect.
After copying, it reads every file back from the destination and compares it byte-for-byte with the original. If anything doesn't match (a corrupted clip, a bad sector, a file that couldn't be read), Byte Check tells you exactly which file and where. You find out before you format the card, not after.
BUILT FOR CARDS AND DRIVES
• SD, CFexpress, CFast and CF cards, SSDs, hard drives, USB sticks and folders
• Works with ExFAT, FAT32, APFS and Mac OS Extended drives
• Remembers your source and destination, even after you unplug and reconnect them
VERIFICATION YOU CAN TRUST
• Byte-for-byte comparison of every file, not just file sizes or dates
• Reports missing, changed and unreadable files, down to the byte where they differ
• Verify Only: re-check an existing backup at any time without copying anything
FAST AND SAFE
• Re-run a copy anytime, and only new and changed files are copied
• Each file is written under a temporary name and put in place only once complete, so an interrupted copy never leaves a half-written file behind
• Keeps modification dates, creation dates, Finder tags and other metadata
• Optional mirror mode makes the destination an exact match of the source
• Dry run shows what would change before anything is written
• Exclusions let you skip files you don't need
PRIVATE BY DESIGN
Byte Check works entirely on your Mac. It doesn't collect data, doesn't need an account and never connects to the internet.
