[ http://issues.apache.org/jira/browse/IO-91?page=all ]
Stephen Colebourne closed IO-91.
--------------------------------
Resolution: Fixed
- FileSystemUtils.freeSpace deprecated, replaced by freeSpaceKb
- freeSpace returns a result that varies by operating system and
thus isn't that useful
- freeSpaceKb returns much better and more consistent results
- freeSpaceKb existed in v1.2, so this is a gentle cutover
- FileSystemUtils.freeSpace [IO-91]
- This is now documented not to work on SunOS 5
> FileSystemUtils.freeSpace does not work on Sun Solaris
