Three files in firmware update archive

[locarno]

Hello
Which file should I choose for firmware upgrade? Or which to install first?

General_IPC-HX5XXX-Volt_MCU_V2.840.0000000.25.R.230425.bin
DH_IPC-HX5XXX-Volt_MultiLang_PN_Stream3_V2.840.0000000.25.R.230425.bin
or
firmware.bin

I only used DH_IPC-HX5XXX-Volt_MultiLang_PN_Stream3_V2.840.0000000.25.R.230425.bin
Which is around 85MB filesize.
