I submit this here for consideration of being added to Commons IO. If this should be directed elsewhere, I would appreciate that information. Thanks for your time! Synopsis -------- A common question I've seen asked (and been asked myself numerous times) is how to get the free space on a volume in a pure-Java way. At the present time, as far as I know, nothing like this exists in the SDKs. So, I set out to write a class that could do it for any platform (almost) without using JNI. It's still not really a pure-Java solution since it uses System.exec to shell out to an OS-specific utility (dir for Windows, df for *nix) to get the information. I have tested this on Windows XP, Windows 2000, Windows NT, RedHat Linux and Mandrake Linux. I believe it will work on virtually any Windows or *nix platform, although the more verification of this I can get, the better! I have purposely left out support for some platforms like AS/400 and OS/390 because I frankly don't know anything about them and don't have access to them to test. Perhaps down down... To use it, simply instantiate a GetFreeSpace object and call the GetFreeSpace() method, passing it a path. This will be a drive letter, including the colon, on Windows, or a mounted filesystem on *nix. An IOEXception is thrown if anything goes wrong, with an at least somewhat descriptive message about what may have gone wrong. Generally-speaking, if used as specified, it should "just work". (Does it make more sense to make this a static method of some other Commons object? Anyone?)
