Local Files

Local files are files created in the cache which do not have corresponding files in external storage. Local files are stored wholly within the cache, and the cache will never attempt to read data into them from external storage, or flush their data out to external storage.

Typically, applications make use of local files in cases where certain files are known to be temporary, or for some other reason should not be written to external storage. For example, Windows' Thumbs.db and desktop.ini files, macOS's .DS_Store files, etc. It is up to the application to determinate the state of, and subsequently manage, all local files.
