File
When you save a document to your hard drive, it becomes a
file. A file has two important features. First, it has a name so that you can
tell it apart from other files. Second, it has place to live, like a home
address.
Folder
A folder, unlike a file, is a storage unit or container.
Like a file, it also has a name. A folder is not a file, but it can contain
files. It is just like a paper folder where you store your important paper
documents such as your paid bills.
