VBF is just a container that has different parts in it. Like SBL, DATA and EXE.
All the downloaded software (VBF files) from VIDA are encrypted. Before writing the software on the ECU, VIDA decrypts and divides it to several smaller VBF files and installs them one by one.
Some ECU such as SWM, HCM reloads requires calibration or configuration procedures run by the VIDA. Some ECUs requires different procedures for software reload like ECM that has a PIN.
FYI protected levels on the ECUs like BSM, CEM, ABS, SRS are written only ones on a brand new ECU that ties ECU to the VIN.
