    Straight to the point:
    - Colleague running Sierra on a Mac Pro just moved a file from a memory card to an external drive.
    - After the transfer was done, he formatted the memory card and then sent it away.
    - Back on his Mac Pro, he accidentally hit CMD+Z while in the Finder-window instead of the app he was using.
    - Finder seem to have undo:ed the "move from memory card to the external drive"-move, but since the external drive is not plugged in anymore the file obviously cannot be found on that drive any longer.

    What actually happened to the file?
    Is there a way to redo the undo (it's currently greyed out).

    Grateful for all the help. Important file and a not so happy colleague.

    (edit, got the process of from what device to what wrong).

    He can probably unerase the memory card using Data Rescue: provided he hasn't added any new date to the memory card. There is a free demo of Data Rescue that will allow you to recover one file without payment.

    Good call by JohnDS above.

    Wherever he "sent" the memory card to, he'd better call quickly and get it back!

    It is simply deleted. There is no clipboard or space where these would be kept. Your colleague probably copied the file, not moved. That makes the deletion logical from Finder’s standpoint. I cannot reproduce this with a file move, as Finder complains with an error message (presumably because it attempts to move the file back to an unavailable location).

    If that's your colleague's Standard Operating Procedure, then it needs to change.

    Files aren't safe until there's at least one duplicate somewhere else. Preferably two copies in two separate places. This is especially true for external media, such as SD cards, USB drives, etc.

    If the hasty deletion and reformat was for security reasons, as in the data needed to be kept from access by others, then learn to make and use encrypted disk images. These are made using Disk Utility, using instructions described here:
