- """AppleSingle and AppleDouble files are used by certain Mac
- applications (e.g. Finder) to store Mac-specific file attributes on
- filesystems that do not support that.
-
- Syntactically, both formats are the same, the only difference is how
- they are being used:
-
- * AppleSingle means that only one file will be created on external
- filesystem that will hold both the data (AKA "data fork" in Apple
- terminology), and the attributes (AKA "resource fork").
- * AppleDouble means that two files will be created: a normal file
- that keeps the data ("data fork") is kept separately from an
- auxiliary file that contains attributes ("resource fork"), which
- is kept with the same name, but starting with an extra dot and
- underscore `._` to keep it hidden.
-
- In modern practice (Mac OS X), Finder only uses AppleDouble to keep
- compatibility with other OSes, as virtually nobody outside of Mac
- understands how to access data in AppleSingle container.
