Types of files

Serial- files are stored one after the other

Sequential- files are in order so that you know what is at the start and the end. Have to make sure its inorder as it allows quicker access.

Indexed Sequential- stored in order, you also have an index telling you where something is.

Direct Access- set chunk of data so you access it it easily.

Random access-stored things all other the disk, so you used an algorithm to find them.
