StellarDriveDefrag is here to help you systematize the fragmented data and free space in the Mac volumes. The software gathers the fragmented data of a file and stores together into a single chunk of memory, which makes the data access speed faster.

  • Defrags the meta-data files in a volume.
  • Optimizes the fragmented free spaces in a volume by clubbing them together.
  • Performs defragmentation on an entire volume and drags files to a contiguous memory location.
