Partition Logic is a free program for partitioning and managing hard drives. The application can create, delete, format, defragment, resize, move and change partition parameters, and even copy partition contents from one disc to another. Partition Logic is based on ViOpSys (Visual Operating System), which starts from a CD or floppy disk.

The application is a very good alternative to other commercial programs of this type such as Partition Magic, Drive Image and Norton Ghost. Since version 0.61 the program supports NTFS partitions.
