The maximum value for a long is 92,233,720,368,547,758,07l (that's roughly 92 quintillion I believe).
One gigabyte = 1,073,741,824 bytes. So, you could potentially represent 8,589,934,592 gigabytes using a long. Is my math off here? -----Original Message----- From: Marcelo Nery dos Santos [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 22, 2005 3:26 PM To: commons-dev@jakarta.apache.org Subject: FileSystemUtils Hi, After studying the Jakarta Commons IO API, I found a great method that allows me to delete some native code from my system, it is the: static long FileSystemUtils.freeSpace(String path) However, as it return type is long, I am in trouble to represent values greater than 2GB. Is it possible to add another method into this class? I would suggest something like: static double getApproximateFreeSpace(String path) Thus, if a general (possibly high) approximate value is needed, this method could be used. In situations where an exact value is needed, typically, when we are running low in space, the original 'static long freeSpace(String path)' would fit. I think this comment is also valid in other areas of the IO package. However, it is more critical when dealing with file system comprising several gigabytes of free space. By the javadoc, it is not clear what value is returned if a free space larger than 2GB if available. Thanks for this great package.
