I have read that it is for compatibility with the Windows 2000 operating system.

Quote: In win2000, the transferTo() does not transfer files > than 2^31-1 bytes. it throws an exception of "java.io.IOException: Insufficient system resources exist to complete the requested service is thrown." The workaround is to copy in a loop 64Mb each time until there is no more data.
