Go or Gio
Hello!
On a a laser disc, you can read 4.7 GB, or 4.7 Go for us French people. OK, but when I put my disc in the drive, all the burning software tells me I can write 4.37 Go.
On Wikipedia, it says DVD-5 single-layer, single-sided: about 4.7 Go (4.377 Gio).
For the past 30 years that I've been into computers, every Windows has always said that 1 Mo is 1,048,576 bytes (1024 X 1024). I've never seen Gio or Mio or Kio on Windows. It's only on Linux or software published by Linux like Filezilla, Gparted...
If 1 Mo = 1,000,000 bytes, why do Windows and all software publishers intending to display file sizes not use Kio, Mio, or Gio?
Thank you for enlightening my dimming lantern... :)

If 1 MB = 1,000,000 bytes, why do Windows and all software publishers aiming to display file sizes not use KiB, MiB, or GiB?

It's a good question, even though some software on Windows does make the distinction, it's true that many remain in this error.
But I confirm, 1 KB = 1,000 bytes and 1 KiB = 1,024 bytes. This is the international standard. The prefix kilo denotes a power of 10, whether it's for grams, meters, or bytes.

ContributorHello,
why do Windows and all software publishers aiming to display file sizes not use Kio, Mio, or Gio?
The explanation is given here:
This distinction (between binary and decimal prefixes) is necessary, as the confusion between the two series of coefficients has been used for a long time by hard drive manufacturers. The fact that using (for the same capacity) prefixes in powers of 10 allows for commercially displaying values higher than those given by powers of 2 can introduce a misjudgment by uninformed users. Thus, a hard drive of 100 gigabytes (100×10⁹ bytes) contains approximately the same number (allowing for rounding error) of bytes as a drive of 93.13 gibibytes (93.13×2³⁰ bytes).
With 100 Go you get your money's worth, while with 93 Gio you get ripped off ;-) -
Moderator@zipe31It explains very well why manufacturers use GiB instead of GB, but not why Windows and some software continue to use GB instead of GiB. ;-)
So thanks, I don't understand why Windows and the like haven't changed their approach? :(
I don't understand either. -
Contributor@PierrecastorI wouldn't want to speak ill, but when you know that we went from W8 to W10, skipping W9 because a part of the code (in the noyal) refers to Windows 95/98 and that it would have caused chaos, I suspect that these stories about Go and GiB could lead to an unimaginable mess ;-))
