A amifldrv64.sys was made in the download folder after doing a bios update for my xps 8920 would deleting it be fine?
I did from the installation instructions
Download and Installation 1. Click Download File. 2. Click Save to save the file to your hard drive 3. Browse to the location where you downloaded the file and double-click the new file. The system restarts automatically and updates the BIOS at the system startup screen. After the BIOS update is complete, system restarts again.
