Definition of folder

The word "folder" originates from the verb "to fold," referring to the act of folding paper to create a container for documents. Its earliest recorded use in English dates back to the 17th century. Initially, folders were simply pieces of folded paper. The invention of the paper clip in the late 19th century led to the development of metal folders, and eventually, the use of plastic and other materials. The term "folder" has since evolved to include digital storage structures, maintaining the concept of organizing and grouping files.
