In specification of the java.io.File there is written:
 Instances of this class may or may not denote an actual file-system object such as a file or a directory. If it does denote such an object then that object resides in a partition. A partition is an operating system-specific portion of storage for a file system. A single storage device (e.g. a physical disk-drive, flash memory, CD-ROM) may contain multiple partitions. The object, if any, will reside on the partition named by some ancestor of the absolute form of this pathname.
---------
public long getTotalSpace() :
Returns the size of the partition named by this abstract pathname.
    
    return The size, in bytes, of the partition or 0L if this
               abstract pathname does not name a partition
---------
Actually, the meaning of the “partition” does not seem to be completely clarified. It would be desirable to have an explanation of the “partition” in terms of different platforms. It looks like “partition” in terms of Windows platform may contain more than one logical drive. What the method getTotalSpace() will return in this case: the size, in bytes, of the whole partition, or just the size of the current logical drive? It is not clear! The same situation is with methods getFreeSpace() and getUsableSpace().
