How I can export a downloaded file in the Memory of my IPhone to my iMac???

[Ero]

I have tested to export the files to my Mac-no success. I can only rename, move or copy, only where??? My iPhone offered me no file or place. Best regards Ero

There should be a "Share" option there, like in the screenshot below. Then from there you can AirDrop it to your Mac or whatever.

What version of iOS are you using? What is the version of the Blackvue app?
I'm using iOS 15.1, and my Blackvue app is "v3.26_3111".
