Files on USB drive, only showed in Bios.

HideoK · Jul 1, 2023

Hello, I formatted (NTFS) my brand new usb pen drive, and copied Bios files, to update the Bios of my motherboard.
But in the Bios it shows some other files, as you can see in the attached pic.
Is this normal?
If I format it in exFat, it isn't showed at all in Bios update menu.

It is normal to see other folders on some BIOS updaters. Some will only allow the BIOS file to appear in the root folder. Maybe the rules are different between NTFS and exFAT on your Updater.

It would help to know which motherboard you are using.

The Bios "Update program", appears be to showing what seem to be NTFS metadata files (only with the $ missing from the names) on the USB which you have formatted as NTFS. Normally such files would be present in the root of NTFS drives although completely hidden from view unless you use a program which can access them such as eg. Wiztree. Perhaps the Bios Update program is able to access/view them?

eg: all these are present on my C: drive but not visible in Explorer (even with show hidden files option selected).

Yes, I read this online. It's weird, because I tried with another older usb stick, and it doesn't have those files.

@iko22 I have a Gigabyte X570 Aorus Elite.

Dunno then, your Motherboard's manual states that the BIOS flash utility only supports FAT32/16/12 formatted USB drives.
