You can have as many logical partitions on your hard drive as you physically have space for them. With our large hard drives today, you may have 3-4 logical partitions on each hard drive with each being less than 8GB in size. In certain cases, you may have a logical partition that is larger than 8GB in size. We will point this out later in our presentation.
	Logical partitions are normally not hidden and are almost always usable. This makes them ideal for storing your application programs and data files.
	All of the logical partitions on a hard drive must be located together inside the extended primary partition. The extended partition is really not a partition that can hold files like primary or logical partitions can. Instead, the extended partition is a holder of logical partitions on each hard drive. Logical partitions are inside the extended partition while primary partitions are outside the extended partition boundaries.
