The documentation that you linked give the answer:
The java.nio.file package defines interfaces and classes for the Java
virtual machine to access files, file attributes, and file systems.
This API may be used to overcome many of the limitations of the
java.io.File class. The toPath method may be used to obtain a Path
that uses the abstract path represented by a File object to locate a
file. The resulting Path may be used with the Files class to provide
more efficient and extensive access to additional file operations,
file attributes, and I/O exceptions to help diagnose errors when an
operation on a file fails.
