I just noticed in File Viewer (random all-files reader) on OS X, that all files have a Misc. attribute called "File Number". It contains values like 17022656, 17022354 and 435457.
I tried to look online for it's meaning, but as it's such a global meaning I couldn't find much of worth.
Does anyone know what this means? Some sort of index in which order files were originally created on the HFS+ partition?
Just curious :)
