Unable to install Windows 10 via Bootcamp on late 2013 iMac?

I'm using an iMac (27-inch, Late 2013) 3.2 GHz core i5, and trying to install Windows 10 via bootcamp. I've downloaded the Windows 10 iso and got an external 32GB USB stick for the install disk (formatted in exFAT). When running bootcamp, it however prompts with the error "Your bootable USB drive could not be created - There is not enough space available on the disk". Would anyone be able to kindly advise where I might have went wrong?

Thanks for the pointer Loner T, much appreciated :)

I've been researching some forums and am glad to inform that I have successfully got Windows 10 up and running via Boot Camp!

The reason I was getting the insufficient space error was because Boot Camp was trying to create the bootable USB drive formatted in FAT32 (which has a 4GB limitation), whereas the Win10 ISO is in the ~5GB range. I followed "Answer #1" in the url below to manually create a bootable Win10 USB drive, formatted in ExFAT. Once done, I ran Boot Camp Assistant and only selected the option to install Windows. From there on it was pretty smooth sailing.

FYI I am still running macOS Sierra 10.12.6.

Thank you and good luck all!

BC Assistant in High Sierra and older does not work properly with W10 1903 and later ISOs. Mojave 10.14.6 has an updated to address the issue - Download macOS Mojave 10.14.6 Combo Update. Catalina should also have the same update.

Issues with partitioning in Catalina and Mojave indicate APFS corruption.

Thanks for mentioning this, I was about to try that but I guess I will not have to now....!

Am actually wondering whether its anything to do with editing the Info.plist configuration file for bootcamp.....

I have also tried using a much larger 160GB external HD drive, however it still comes up with the same error message "Your bootable USB drive could not be created - There is not enough space available on the disk".

It looks like it might be a bug within Boot Camp Assistant?
