How to back up a Fujifilm card on Mac

Q: Is dragging the Fujifilm card to my drive in Finder safe enough?

A Finder drag copies the files but does not verify them, so a silent read error or dropped byte can corrupt a clip without any warning. Copsy verifies every file with ASC-MHL checksums after copying, so you know each clip copied bit-for-bit before you reformat the card.

Short answer

Copsy — a free Mac camera-offload app — is the simplest safe way to back up a Fujifilm card. Drop your X-H2S, X-H2 or GFX SD / CFexpress card into a reader and Copsy copies the footage to your drive and to Google Drive or Dropbox in parallel, verifies every file with ASC-MHL checksums, organizes it by date and source, then pings you on Telegram when it's done. Free, no card limit, no signup.

It handles whatever the card holds (internal ProRes on CFexpress or H.265 on SD) and never lets you reformat until the copy is verified.

What Fujifilm X and GFX cards actually hold

Fujifilm's video-capable bodies write to SD and, on the higher-end models, CFexpress Type B. The format on the card decides how careful you have to be:

Internal ProRes — on bodies like the X-H2S and GFX100 II, internal ProRes 422 / 422 HQ records to a CFexpress Type B card. These are large, intra-frame .MOV files where every frame matters, so a single corrupted clip is a real loss. (Last verified June 2026 — always check your body's manual.)
H.265 / HEVC & H.264 — high-bitrate .MOV / .MP4 long-GOP files that fit on a fast SD card, often shot in F-Log / F-Log2 for grading.
Stills + video mixed — Fujifilm shooters frequently mix RAF stills and video on the same card, so a copy that grabs everything matters.

Whatever the body and card, the offload job is the same: get every file off, prove it copied perfectly, and keep a second copy — before you format.

Back up a Fujifilm card on Mac, step by step

Insert the card. Put the SD or CFexpress Type B card in a reader connected to your Mac. Copsy reads the footage. Don't reformat the card yet.
Pick destinations. Choose an external drive, plus optionally Google Drive or Dropbox. Copsy copies to all of them in parallel.
Let it copy and organize. Copsy copies the clips and organizes them by date and source, so your ProRes and H.265 files land in a clean structure instead of a loose dump.
Verify with ASC-MHL. Copsy checksums every file with ASC-MHL, the film-set / Netflix-delivery standard, to confirm each clip copied bit-for-bit, then sends a Telegram message when it's done.
Format only after verify. Once Copsy confirms the copy verified, format the card in the Fujifilm body for the next shoot.

Why not just drag the card to a drive in Finder?

Finder copies — it doesn't verify

A Finder drag moves the bytes but never checks them. A silent read error off a hot card, a dropped byte, or a half-finished CFexpress eject can corrupt a ProRes clip with no warning at all, and you'll only find out in the edit, after the card is wiped. Verified offload tools exist so that "it looked like it copied" becomes "it provably copied." Copsy does that ASC-MHL verification for free.

Free alternatives, honestly compared

If you only need verification and don't mind more manual steps, there are other free options worth knowing:

DaVinci Resolve Clone Tool — free, copies and verifies with xxHash; great if you already live in Resolve, but it's a copy tool inside an NLE, not a parallel-cloud offloader.
MhlFileVerify — free, but verify-only; it checks an existing MHL, it doesn't do the offload.
Terminal shasum / md5 — free and accurate, but fully manual and easy to get wrong on a tired night.
Finder drag — free, but not verified. This is the risky one above.

Copsy's pitch against all of these: one app that auto-detects the card, copies to a drive and the cloud in parallel, ASC-MHL-verifies, organizes, and tells you when it's safe to format, for free.

Frequently asked questions

How do I back up a Fujifilm card on a Mac?

Put the Fujifilm SD or CFexpress card in a reader, open Copsy, choose an external drive (and optionally Google Drive or Dropbox), and let it copy. Copsy verifies every file with ASC-MHL checksums and organizes the footage by date and source, all free, with no signup.

Which Fujifilm cards record internal ProRes?

On bodies like the X-H2S and GFX100 II, internal ProRes (ProRes 422 / 422 HQ) records to a CFexpress Type B card, while SD cards are used for H.265 and other formats. Always check your specific body's manual. Copsy copies and verifies whatever the card holds, ProRes or H.265, regardless of card type.

Is dragging the Fujifilm card to my drive in Finder safe enough?

A Finder drag copies the files but doesn't verify them, so a silent read error or dropped byte can corrupt a clip without any warning. Copsy verifies every file with ASC-MHL checksums after copying, so you know each clip copied bit-for-bit before you reformat the card.

Can Copsy copy my Fujifilm footage to a drive and the cloud at once?

Yes. Copsy can copy your Fujifilm footage to an external drive and to Google Drive or Dropbox in parallel during the same offload, so your local backup and cloud copy happen together.

Does Copsy work with Fujifilm even though it isn't in the auto-detect list?

Yes. Copsy auto-detects several brands by content (Sony, ARRI, Blackmagic, RED, Canon, drones, audio recorders), and it also works with any card it can read, including Fujifilm X and GFX SD and CFexpress cards. The copy, organize and ASC-MHL verify workflow is the same.

Is Copsy really free for Fujifilm shooters?

Yes. Copsy is free to download and use today, with no card limit and no account required. It runs on macOS 13 or later.
