Embedded Files
Folders are containers for keeping programs, files and other folders. It can be used to organize information on a computer. Whereas, a file is an object on a computer that stores data, information, settings, or commands used with a computer program.
A file is the common storage unit in a computer, and all programs and data are "written" into a file and "read" from a file. A folder holds one or more files, and a folder can be empty until it is filled. A folder can also contain other folders, and there can be many levels of folders within folders.
Folders within a folder are technically known as "subfolders," but this distinction is often disregarded.
Folders are also called "directories".
