Do you think the recovery partition on your hard disk drive (HDD) or solid state drive (SSD) is taking up your disk space? You can actually copy recovery partition to USB drive and delete recovery partition to free up space. If you have a small HDD or SSD, disk space is more precious.

After running Windows 10/8/7 for a long while, Windows update, system files, page files, installed programs, and your personal files may have use a lot of your disk space. Besides Windows recovery partition, some brands of computers have a factory recovery partition (also called OEM recovery partition), which will usually consume more than 10GB of free space.

Factory recovery partition
