Universal Pathname Form (was Re: Finding all mounted volumes)

Greg Guerin <email@hidden> wrote:

By the way, the closest thing I can think of to a universal pathname form
is a URL. But File.toURL() may not cut it, because it will encode the host
platform's idea of a URL, which is not the same as a portable URL. That
is, move the media to another platform and the URL may be different. This
shouldn't be too surprising, since URL's were never intended for doing this.


Actually, that would be a URI, which doesn't cut it either.

Not that we could use it yet anyway :)


<http://java.sun.com/j2se/1.4/docs/api/java/io/File.html#toURI()> says:

For a given abstract pathname f, it is guaranteed that

new File( f.toURI()).equals( f)

so long as the original abstract pathname, the URI, and the new
abstract pathname are all created in (possibly different invocations
of) the same Java virtual machine. Due to the system-dependent nature
of abstract pathnames, however, this relationship typically does not
hold when a file: URI that is created in a virtual machine on one
operating system is converted into an abstract pathname in a virtual
machine on a different operating system.
