Lesson 16 Flashcards
Use Metadata, Spotlight, and Siri
What’s file system metadata? What are some examples?
Metadata is information stored outside of a file or folder. It provides additional information about files and folders. Examples include file flags, extended file attributes, and permissions.
What are some of the common file flags used by macOS Mojave?
Locked flag, which locks files from changes, and the hidden flag, which hides the item in the Finder.
What are file system tags? Where can you find tags in the user interface?
File system tags are a type of metadata that allows you to quickly assign keywords, or “tags,” to any item. A user can customize the tag names and colors and can create multiple tags for a single file.
How does the Spotlight search service use metadata?
The Spotlight search service creates index databases of file system metadata so that it can perform normally time-intensive searches almost instantly. File system tags can be found in the Finder sidebar, Spotlight search, and any Open or Save document dialogs.
Where does Spotlight store its metadata index databases and its plug-ins?
Stored at the root of every volume in a /.Spotlight-V100 folder.
What are some privacy and security concerns with Spotlight?
Other users can search the contents of locally attached nonsystem volumes when ownership is ignored on those volumes.
How should you resolve an issue where a Spotlight search doesn’t find the correct items?
You can force Spotlight to rebuild the index databases by deleting them and restarting your Mac or by managing the Spotlight preferences.
How can you ensure that Siri doesn’t send audio recordings to Apple?
By disabling Siri from Siri preferences.
