File folder
A file folder, also called a folder, is a type of folder that can hold pieces of paper together. Folders are used both to organize pieces of paper neatly and to protect pieces of paper from falling off. Folders are usually made of a thick piece of folded paper, but there are folders that are made of plastic.
The popularity of the folder has led to modern computers using a type of data storage called a folder.
