Merge Folders on MacOS

While migrating my photo library from Google Photos to a new service, I came across a small issue: Google Takeout splits massive libraries into multiple zip files, each containing parts of the same folder. I was mentally preparing to manually file shuffling but then MacOS came to the rescue with a surprisingly elegant folder merging feature.

Here’s the magic trick:

1. Create a new temporary folder
2. Place the first folder inside (let’s call it “target_folder”)
3. Rename the second folder to “target_folder” as well
4. Drag the second folder into the temp folder while holding the Option key
5. MacOS will prompt you to merge the folders

That’s it, done.
