As I said, the size reported by '-s' agrees with the one reported by dir.

But 'dir' is not omnipotent, and there are things like sparse, encrypted and compressed files, where there's no obvious size to report. Check ls command manual, it's got myriad of switches for a reason.

Problem was too much magic in perl file handling (or rather my lack of knowledge on that subject), and binmode fixed that.

    An operating system should not know anything about the contents of a file. What it should know is how many bytes on a disk that file occupies. So, the sparsity, encryptedness, or compressedness should not hinder the OS from knowing how many bytes that files takes up on disk.
