i downloaded defraggler yesterday. started defragmenting today and during the proccess i notice free disk space is going downwards. started with 145gb free space and defraggler has made it go down significantly its down to 130gb free space. defragmenting is not done yet so i am wondering, will the free disk space go back up once defragmenting is done? because i though defragmenting would help free up space.. not take space.. please someone reply to me as soon as possible.
