[Solved] The file install.wim is too large

When you try to create a bootable USB key with a FAT32 filesystem, you may encounter the following error message if your install.wim file is larger than 4 Gb.

This can easily be solved by splitting the install.wim file into two or more .swm files of maximum 4 Gb with the DISM command.

However, you must execute this command on a Windows Server 2012 or Windows 8 system or above, because the Split-Image parameter is only starting with those operating systems.

For example:

DISM /Split-Image /ImageFile:g:\sources\install.wim /SWMFile:f:\sources\install.swm /FileSize:4096
