Correct error in linked guide
Because of the need to split the install.wim file when making a Windows ISO drive, the command given in the linked guide requires some correction. The rest of the guide is accurate.
You can use /FileSize argument instead. See this article for more details: https://www.dell.com/support/kbdoc/ru-ru/000127789/windows-10-iso-contains-wim-file-that-is-big-for-fat32-file-system?lang=en#Split. Can you update the changes?
You can also use ExFat, as long as ExFat driver is provided by OpenCore.
That Dell page details how to split the install.wim file, not how to install the split file. I have added the ExFAT info to the guide.
@brandazzle your "file into two .swm files" is not correct, because you may have to split the file wim file into more than two files if the original is over 8 GB. The Dell website suggests a more adequate command (through /FileSize:4000), which splits into as many files as necessary, that's why I want the dism command here to change.
@vit9696 I'm sorry for the misinterpretation. Thank you for correcting my error; I have updated the command.
