Is there a Java equivalent of GetCompressedFileSize?

Question

I am looking to get accurate (i.e. the real size on disk and not the normal size that includes all the 0\'s) measurements of sparse files in Java.

In C++ on Windows one

Answer 1

Since an answer was given for windows. i will try to supply for Linux.

I am not sure, but i think it will do the trick (C++):

#include 
ioctl(file, BLKGETSIZE64, &file_size_in_bytes);

This can be loaded in the same way that was described in the @Aniket answer (JNI)
