Does any operating system or commonly used program report file sizes in terms of 1 GB = 10^9 bytes? As far as I know they all use GiB and MiB, whether they call it that or not.
- tatref 13y agoWindows uses GiB, but displays GB. On Linux, most tools uses standard SI (1000 = K, 1024 = Ki), but not all of them...
- m_mueller 13y agoOSX has switched to 10^9 bytes a few iterations ago.
- TillE 13y agoSnow Leopard apparently, which was released in 2009. Ubuntu's policies on the subject seem to be about the same age. I suppose I should've said that up until five years ago, nearly everyone was using powers of two for file sizes. And Windows/Mac never used the correct prefixes.

- tatref 13y agoI don't think that giving the users something that _is_ wrong is a better solution... Why not switching to GiB? Power users would understand, and others wouldn't even notice!
- twic 13y agoI remember seeing a French Mac many years ago (pre-OS X). I don't know what kind of mega it used (there was no giga back then), but file sizes were reported as "Mo" rather than "MB", for "mega-octets", "octet" being the French word for byte. It sounded much classier to me. Of course, aficionados of RFCs will know that "octet" is (or at least was) the preferred term for "byte" in IETF documents as well. I don't think this is because the RFC editor was secretly French, although i'm sure he was thoroughly classy; presumably it's because early RFCs were written in the era when the byte had not quite settled down at eight bits, and needed to be unambiguous.
- paulnechifor 13y agoNautilus and Thunar (to name a few) in Ubuntu use SI prefixes.
- kijin 13y agoLinux is all over the place. For example: $ dd if=/dev/zero of=/dev/null bs=1M count=1K 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 0.157131 s, 6.8 GB/s 'dd' interprets command-line arguments "M" and "K" as 2^20 and 2^10 respectively, but when it reports the total amount copied, it uses the decimal GB (10^9). It also uses decimal SI units in the average speed calculation. My favorite file manager, Thunar, reports file sizes in decimal units. Not sure if it's distro-specific, though. Many other programs, like 'df', have a switch (--si) that turns decimal units on or off.
- ambrop7 13y agoXFCE (Thunar) uses SI units (just verified against ls -l).
- cnvogel 13y agoIt depends, sometimes it's even switchable, e.g. take df. $ df -k / Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda3 151798672 47602008 102615608 32% / $ df -h / Filesystem Size Used Avail Use% Mounted on /dev/sda3 145G 46G 98G 32% / $ df -H / Filesystem Size Used Avail Use% Mounted on /dev/sda3 156G 49G 106G 32% / (-h "human readable" with powers of 2^10, -H "human readable" with powers of 10^3) $ df --version df (GNU coreutils) 8.22 ls has -h/--si/-k ... $ ls -h -l /proc/kcore -r-------- 1 root root 128T Apr 6 19:02 /proc/kcore $ ls --si -l /proc/kcore -r-------- 1 root root 141T Apr 6 19:03 /proc/kcore (/proc/kcore is 2^47 = 140737488355328 = 128 * 2^40 = 128 TiBi bytes)
