I'm sure this has been covered before in various places, but I haven't been able to find it in the forum or in the help section of the program (where I think it should be!).
Can someone please spell out the difference between:
- Defrag Files
- Defrag Drive
- Defrag Freespace
- Defrag Freespace (allow fragmentation)
What are the pros and cons of each function? Why would a user run each one (the merits of Defrag Files are pretty well known, but what about the other functions)?
And when I schedule defragmentation (thank you, Piriform, for this feature), which of the above options is the program launching?
