Say I have a video or even a photo stored in my iPhones’s camera roll(the Photos app).
- I save it to Files(inside a folder)
- Connect the phone to my Mac
- Copy the enclosing folder using the Finder>iPhone>Files tab
- Now I have the file on my computer
Now… lets do the same, but with AirDrop
- Select the file from the Photos app
- Airdrop to my Mac.
- Now I have a second copy of the file on my computer
On first glance they look the same: same name and the byte count is(for the most part) the exact same. But, if I compare the two files with the command ‘diff’ it says they are different. Using an application to compare files byte-by-byte reveals that the top part, the header, is what differs. The files will be 99% the same. Does anyone know the specifics of how Airdrop and copying to Files causes the difference?
There are also cases where the files differ in byte count. I would like to find a way to identify these duplicates and delete them.
