Free space of harddisk

Posted: Feb 11, 2003 9:19 PM

Is there any way to be able to determine the total space and available free space of all harddisk in Java?(Do not use native code-100% pure java)
Thanks!

Yes, you use 100% pure Java to determine what platform you are using, then use JNI for that platform. Many platforms don't even have disks and many that do don't represent them as drive letters, as DOS/Windows does.

Thank you, a "Stupid" Answer, :lol:
If you use JNI, you must write native code for each platform. And you lost the Java platform-independent power. And, your program is not 100% Pure Java.

The point I was trying to make was that the idea of "disks" doesn't exist on every platform, so it is a platform-dependent question.
