If there is an extended attribute of type containing an image thumbnail, that is shown as a document-specific icon.

Where a smaller image is required, the document icon is used, according to a system of priorities: Those previews are managed by Quick Look, and are not stored in metadata. Where possible, larger images of documents are displayed using a thumbnail created by Quick Look, and reflect the content of the document, or show a front page with a tool to play media such as audio and movies. This rather unexpected behaviour makes Finder Comments rather too ephemeral for most day-to-day uses.įile-specific settings for the default app of a document are stored in an extended attribute of type, but defaults are maintained by macOS Launch Services. The Finder keeps the extended attribute and its central store in sync, when you move the file elsewhere its extended attribute may be preserved, but the Finder Comment lost, as it is not usually added to the local store of the destination. Although macOS stores the text in an extended attribute of type :kMDItemFinderComment, the comments themselves now appear to be stored centrally, perhaps in a Finder database. It is not an extended attribute, but part of the normal macOS attributes for files.įinder Comments are under user control, being displayed and edited here, in the Get Info dialog. So this date and time represent the moment that a user-controlled app or similar opened them. Services such as Quick Look and the Finder itself can peek inside files to obtain metadata and similar information without their being recorded as opening the file. The Last opened datestamp is particularly useful, but is not quite correct. One which it will display in such cases are the keywords stored in :kMDItemKeywords if present. The Finder may instead show another extended attribute in More Info if there is no :kMDItemWhereFroms attribute. Once present, there is no simple way for the user to remove it.

Although displayed here, when present, it is not controlled by the user in the way that Finder Tags are, but attached to downloaded files by the app or service which downloads them. The next extended attribute is found in More Info, where the Where from entry is taken from the extended attribute of type :kMDItemWhereFroms. MacOS has many more standard attributes to display, and most of the more important ones follow in the General section. Indeed, they are the only extended attribute over which the user is given complete control. I have explained here how they work, using extended attributes. These can be very useful metadata which you can customise, and control in the Finder. text which are helpful to the system and meaningful to humans.īelow the name, size, and datestamp of last modification, macOS shows any Finder Tags.

If you want to make full use of macOS, use extensions such as. Extensions don’t have to be MS-DOS-style and limited to three characters.

Classic Mac OS didn’t use extensions (or, rather, they didn’t mean anything to it, as it typed files according to the Finder Info), and there is still resistance from some users. The filename and its extension are the most fundamental attributes of a file, and key metadata. The best place to start examining metadata is in the Finder’s Get Info dialog, which provides the most ready access to much of the metadata for each file. Although the author information can be embedded in the text itself, when it is attached as a separate piece of information, it becomes metadata.

It can be very simple: a plain text file can have attached metadata containing details of the author, and inevitably has basic file attributes such as the date that it was created. Metadata means information about the data in a document, as opposed to the content of the document itself. This article looks at some of the most commonly-encountered metadata associated with Mac documents, explains where it is stored, and how it can be altered. There seems to be some confusion as to what metadata is, and where it is stored.
