Copy - Paste in Java, fastest method

Hi everyone.

I know java has no way of doing this by default but I can't seem to find a really good solution. I am making some software with copy paste file functionality built in and of course I need to be able to copy paste files as quickly as possible.

Another thing I am trying to do which java won't let me do is find out the size of my hard drives and how much of them are used up.

The copy paste problem is more important to me though. Anyone know of a quick way to transfer a file of say several megabytes.

Thanks!

Copy & Paste a file?

Do you want to put a file reference into the clipboard, so you can later "paste" it to a different place like Explorer does? Or do you simply want to copy it?

I'm afraid I can find no call that directly interfaces any system-level copy routines, so you'd have to copy yourself. Allocate a byte buffer about 32k large and just read that much in and write it out. Repeat until finished.

or make it in C++ and use it in your application...
