    EbuDllTmpDir folder with a BiosUpdate.bio file

    A couple of months ago I hired a guy to fix some issues in my old PC, and one of the things he did was to update the BIOS.

    Now I have this EbuDllTmpDir folder with BiosUpdate.bio file on the C: drive. Its size is 3.760 KB and it's the only .bio file and the only file with ebu in its name I found on the system using Windows 10's search.

    I searched over the Web prior to posting here but couldn't find much. I tried "Ebu dll" and the closer I got was to ebueula.dll.

    I wonder if I can delete that folder without causing any harm. Seeing that Tmp part in the file's name made me think it could be something temporary that should be deleted after the procedures that created it, but I'm not sure.

    Any ideas? TIA.

    Before deleting anything,backup to another drive,Macrium Reflect is a good programme.
    Disconnect all drives except that which has the file to delete,then delete the appropriate file.
    If you encounter any problems after the deletion,you can restore from the backup.
    Whenever you have doubts,backup first.

    I can think of two things those files can be...

    1. Most motherboards will let you update the BIOS from within Windows. Those could be the leftover files.
    2. Some motherboards let you save your BIOS settings to file on one of your drives. Again, those could be that.

    It's probably safe to delete, but back it up first.
