What is a partition
When new, drives are basically just one mass of storage space but in order to set up a filing system and save these files to a drive, it needs a partition.
Sometimes a single partition is all that needs to be created on a drive, or in other cases there may be twenty or more, however at least one partition is a necessity.
It is not possible to write files to a blank disk, there needs to be a container for a file system, which is called a partition
Once the partition is created it is formatted with a file system and when files are written on the computer, they can be directed to that partition.
If, for instance, you are using a USB flash drive and decided to create multiple partitions on it, these would each show up as different drives when plugged into the computer.
A good use for partitions is for personal files on a pc. If it is necessary to re-install windows, you can do so and your personal files, stored on a separate partition, will still be safe.
