FileStore... getRootPath() ?

[John Hendrikx]

Dear list,

I have a use case for NIO2, where I wish to present the user with a list 
of FileStore's (or roots) from which to select one depending on 
available space on the store.  A loop as follows gives me the relevant 
information in Java at the moment:

for(FileStore store : FileSystems.getDefault().getFileStores()) {
  System.out.println(store);
}

This will print a list like this:

(C:)
data (D:)
New Volume (F:)
etc...

or on Linux:

/ (/dev/hda2)
/lib/init/rw (tmpfs)
/proc (proc)
/sys (sysfs)
/proc/bus/usb (procbususb)
/dev (udev)
/dev/shm (tmpfs)
/dev/pts (devpts)
/sys/fs/fuse/connections (fusectl)
/data (/dev/md0)
/temp (/dev/mapper/temp)
/raid1 (/dev/mapper/raid1)
/raid2 (/dev/mapper/raid2) 


It is fairly trivial to filter this list to only the stores useful to 
the user (by discarding items with "non-sensical" 
useableSpace()/totalSpace() values, ie. both being zero).

However, it turns out that after finding this treasure of information, I 
cannot make use of it without parsing toString() of FileStore, as there 
is no method to go from a FileStore to a (root) Path.

Is this an oversight or is there perhaps an even more elegant way to 
find this information?

Note that even on Linux, with just "one" root (/), the added choice for 
other volumes (which have different free space values) is invaluable for 
the user.  In other words, I'd like to present the user with the choice 
of for example: /, /data, /temp, /raid1 and /raid2.

Thanks,
--John
