True or False: When restoring a File Backup, SRAM files on the controller are overwritten.

When a File Backup is restored on a FANUC controller, the SRAM (Static Random-Access Memory) files indeed get overwritten. This is because the File Backup includes all necessary data that has been saved, including system configurations, programs, and other relevant parameters stored in SRAM.

The purpose of a File Backup is to restore the system to a prior state, ensuring that all information is brought back exactly as it was when the backup was created. As a result, restoring this backup effectively replaces the existing SRAM files with the ones from the backup, making the statement true.

The other options suggest varying conditions under which SRAM files might not be overwritten, which does not align with the standard behavior observed during a File Backup restoration on FANUC controllers.
