Java File.length() vs File.getTotalSpace()

[sees_all1]

Anyone know the difference between the two?

 

Also, if I wanted to make an exact copy of a file, would File.getTotalSpace() necessarily have to be the same between the copies, especially between different operating systems?

[spoiler=length]length

public long length()Returns the length of the file denoted by this abstract pathname. The return value is unspecified if this pathname denotes a directory.

 

Returns:

The length, in bytes, of the file denoted by this abstract pathname, or 0L if the file does not exist. Some operating systems may return 0L for pathnames denoting system-dependent entities such as devices or pipes.

 

[spoiler=getTotalSpace]getTotalSpace

public long getTotalSpace()Returns the size of the partition named by this abstract pathname.

 

Returns:

The size, in bytes, of the partition or 0L if this abstract pathname does not name a partition

 

 

You Probably want to use length because from what I can tell getTotalSpace is for checking information on Drives (and possibly folders) Contained disk space.
