Renaming BIOS Update File Or NOT?

[drpeppercan]

I am so confused. I've found information saying to rename the BIOS Update file to "gigabyte.bin". But others say not to, to just leave the original name. If I change the file (rename, edit, repack), Q-Flash may reject it or worse, flash incorrectly. So, which one is it?!!
