-For imagefile, you will enter the destination of the install.wim file on the partition where you copied it
-For applydir, you will enter the destination of the Windows installation partition
eg : dism /apply-image /imagefile:D:\install.wim /index:"1-11" /applydir:C:\
Method 6 : Dism /Split-Image /ImageFile:"install.wim path" /SWMFile:"install.swm path" /FileSize:3800
-For ImageFile, you will enter the destination of the install.wim file inside the Sources folder on the partition where you mounted the ISO
-For SWMFile, you will enter the destination of the install.swm file in the Sources folder on the FAT32 partition you created
eg : Dism /Split-Image /ImageFile:F:\sources\install.wim /SWMFile:W:\sources\install.swm /FileSize:3800
-The command Dism /Split-Image is used to split a large single .wim file into multiple smaller files (which use the .swm extension).
-UEFI systems usually require the USB drive to be formatted as FAT32.
-The FAT32 file system has a strict limit: it cannot store any single file larger than 4GB.
-Modern Windows install.wim files are often larger than 5GB.
-The Solution: You use /Split-Image to chop the 5GB file into two smaller files (e.g., 3GB and 2GB) so they fit onto the FAT32 USB drive.
