Hidden Folder vs macOS Hidden Files
Apple's developer documentation treats hiding on a Mac as a display matter. The Finder and some other interfaces hide files with a dot name, and the hidden flag is a "hint that the file should be hidden in the GUI". Apple does not describe hiding as encryption. A vault is planned to encrypt files and keep the names out of sight too.
Hiding a file and protecting a file are two different jobs.
Verdict. Hiding is a built-in display hint. A vault is planned to add encryption and a lock.
Pick macOS hidden files if
- You only want less clutter in Finder.
- Nothing in the files is sensitive.
Pick Hidden Folder if
- The files would cause harm if someone saw them.
- You share the Mac with other people.

How hiding works
Apple's File System Programming Guide says the Finder and some other interfaces, such as the Open and Save panels, hide any file or directory whose name starts with a period. The same guide lists a hidden flag, UF_HIDDEN, with the command name hidden, as a "hint that the file should be hidden in the GUI". The file owner or the superuser can change it. Apple's page on hiding a user account shows the command sudo chflags hidden.
Where hiding stops
- Apple calls the hidden flag a hint for the GUI. It does not describe it as a lock.
- Apple says Cocoa interfaces such as
NSFileManagerdo not filter out items that are normally invisible to users. Code that uses them sees the full file system, within normal permissions. - Apple does not describe encryption for hidden files in the pages we read.
