Free Partitioning Software

The partition table editors listed on this page allow you to create, resize, move, concatenate, copy, undelete (unerase) the partitions that you have on your hard disk (or hard disks). For example, if you wish to create more partitions from the existing one (or more) that you already have on your disk, these tools will allow you to resize the existing partition to make space for more partitions without losing your data that is currently on your existing partition. They can also assist you in creating, and sometimes also formatting, new partitions. Some of the tools may have the ability to slide your partition, that is move your existing partition from one location on the disk to another location, without losing data, as well as convert a partition from one type to another (for example, converting from NTFS to FAT32 or vice versa). Still others may be able to help you recover partitions that you have already deleted, that is unerase or undelete partitions.
