Storage unit prefixes of selected files are incorrect (byte <> mebibyte)

[Redglyph]

Hello,

I've used Total Commander since... well, since it was called Windows Commander. But I had never noticed this, the prefix of the indicated storage size is wrong.

If I select a file of 16,383 bytes, it's shown as "15 k" at the bottom, and if it's 16,384 bytes, it's "16 k", which indicates it's displaying kibibytes (abbreviated KiB) and not kilobytes (normally abbreviated kB though some use KB).

As you can verify on the NIST website (or the dictionary, or even Wikipedia if you dare trust this website), kilo- is used for powers of 10, even with computer storage units. The binary storage units have been standardized in 1998 to avoid this confusing situation. See for example:

https://physics.nist.gov/cuu/Units/binary.html

To be fair, the Explorer makes the same mistake (I had to check since I'm never using it).

I know some of us used to consider powers of 2 instead of powers of 10 for those units but it's not been the case for more than 20 years. Perhaps an option to choose, or at least the proper prefix could be shown?

PS: This has actually caused a problem when I thought I had enough space to transfer a series of big files and looked at the bottom to see the number of MB they used.

This is not a new topic
and I guess many users prefer to have the same display in Explorer and a 3th party file manager.
If this would be changed there would be much more complains
compared to the theoretical discussion what the right units are.

You can actually switch to 1k = 1000b instead of 1k=1024b if you prefer. However, it only affects locations within Total Commander, it doesn't affect dialogs which are part of Windows, like the properties dialog (Alt+Enter).

You need to add the following line to the file wincmd.ini, under the [Configuration] header:
SizeStyle1000=1

You can edit the wincmd.ini via menu Configuration - Change settings files directly.

I guess most don't care, they still use 1024, and they are right imo.

I don't care;-)
I'm using "Size display: bytes" and "Header/Footer: bytes"

Hi, so if i set this value  SizeCheck=1  for Tc there will be no difference between being configured with  SizeStyle1000=0  or  SizeStyle1000=1

And if i want Tc to use the same data size standard that hard drives manufacturers use, i should set  SizeStyle1000=1  on Wincmd.ini

Am i right?

Thank you .

Yes, SizeCheck=1 only makes TC check if there is enough disk space on target before copying.
This function works independently from the value of SizeStyle1000, because SizeStyle1000 only determines how the sizes are displayed. SizeCheck compares the file size to the free space (both measured in bytes).

Does SizeCheck=1 take cluster size into the equation as the cm_GetFileSpace (Ctrl+L) command does?

[ghisler(Author)]

Yes it does!

Thanks, that's most helpful!

I don't see why TC users would use Explorer, nor why there would be any complain. It's not a theoretical discussion, it's a real problem when comparing available space, as mentioned in the first post.

You're right, it's your opinion Why would they be right though?
