Troubleshooting: file copy fails

It can possibly happen when Windows image file is over the FAT32 file size limit of 4GB. When it happens:

  • Copy all the content except the Windows image file (sources\install.wim) to the USB drive (either drag and drop, or use this command, where D: is the mounted ISO and E: is the USB flash drive.)

robocopy D: E: /s /max:3800000000


  • Split the Windows image file into smaller files, and put the smaller files onto the USB drive:

Dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:E:\sources\install.swm /FileSize:3800

Note, Windows Setup automatically installs from this file, so all you need to do is name it install.swm.
