Files size() method in Java with Examples
size() method of java.nio.file.Files help us to get the size of a file (in bytes). This method returns the file size, in bytes by taking the path of the file as a parameter. The size may differ from the actual size on the file system due to compression, support for sparse files, or other reasons. The size of files that are not regular files is implementation-specific and therefore unspecified.

- IOException if an I/O error occurs.
