# Improving Hard Drive Performance * Windows needs at least 15 percent free space on the hard drive * Uses it as working space * Uninstall software you no longer need and occasionally delete unneeded files * Disk Management includes a Disk Cleanup (cleanmgr.exe) utility * Deletes temporary files on the drive * A hard drive can be optimized to improve performance: * For magnetic hard drives, Windows automatically defragments the drive once a week * To defragment is to rearrange fragments or parts of files on the drive so each file is stored on the drive in contiguous clusters * For SSDs, Windows automatically trims the drive weekly * To trim an SSD is to erase a block on the drive that is filled with unused data
