Often a program operates on
a disk file as a whole―renames it,
checks if it exists, deletes it,
or alters its properties.
These operations are performed by
using the methods of
the class File
.
The class is also used for
working with directories.
Using the File
class will greatly improve
programs that read or write disk files.
