1. defrag.exe - It is perfectly safe to defrag using this method.
2. You should use defrag.exe. When defrag actually runs, it will run
dfrgfat.exe if the drive being defragmented is FATx and dfrgntfs.exe if the
drive being defragmented is NTFS.
The defrag console (drrg.msc) does the same thing. Runs dfrgxxx.exe based
on the file system being defragmented.
