I encountered an issue that USB thumbdrives created for UEFI only has 32G in FAT32 and files larger than 4G cannot be copied to it due to limitation from FAT32. Here is a solution:
To split a windows image file:
Dism /Split-Image /ImageFile:m:\rollout\Win10.wim /SWMFile:m:\rollout\splited\win10.swm /FileSize:4000
To apply a slited image file:
dism /apply-image /imageFile:m:\rollout\splited\install.swm /swmfile:m:\rollout\splited\install*.swm /applydir:m:\rollout\splited\applied /index:1
