ISO file size discussion

Size of install.wim and included content seem to depend on language version.

For test I download build 22579 fi-fi ISO and it has install.win with 10 different Win 11 editions.

Compared for your screenshot fi-fi package didn't have Home SL was missing on f-fi package.

Hi Pauli,

Thanks, clearly the ISOs are different in different areas. One less edition seems to be enough to get the install.wim below the 4GiB limit.

The one I got with 11 editions was too big for FAT32 and had to convert to .esd just for the Pro that I need.

Another extra pain in the neck for the user.

@suat.cini,

Still confusion with GB versus GiB. 🙃 To avoid that MS confusion I use Bytes instead of GB or GiB.

Use dir command from command prompt to see the actual size in bytes.

Anyway, the ISO I got here in the US has 11 editions, yours has only 6.

Also, the FAT32 file size limit is 4GiB= not 4GB

Convert GiB to bytes - Conversion of Measurement Units (convertunits.com)

Created .esd for the Pro edition only:

@Sibro,

The install.wim in the MS ISO is too big to fit on a FAT32, so I will have to convert it to install.esd. 🤷‍♂️

Above the FAT32 limit of 4,294,967,296 

Hi.

My install.wim in the MS ISO is just 3.75 GB.

Hi suat.cini,

Your shot shows 3,938,001 KB so it is more than 3.75 GB 😏 it is 4,032,513,024 bytes which is still below 4GiB. My file below shows 4,234,191 KB x 1024 is above 4 GiB

Perhaps you did not get all the editions. I downloaded it today from MS Insider right after it showed up on the blog.

Different zone and language?

Hi fg2001,

MS ISO downloaded from MS site includes all versions, I guess. It is not up to me to choose which editions I download.

File size is taken from Windows Explorer. But I can also reach the same size through calculation.

File size is 3.75 GB from Windows Explorer. Or 3,938,001 KB/1024/1024=3.755570411... GB (=3.75 GB rounded to two digits)

My zone is different, it that makes any difference in wimfile size.
