What is a File?
Any data on a computer is stored in the form of a file. That is why a file is said to be a collection
of logically related data. Each file has its own unique name, which is made up of two parts
separated by a period(.).
The two parts of a file are:
File name: A filename can consist of letters, numbers, spaces, and characters.
File extension: This identifies the file type and the application it belongs to.
For example:
Mynotes.docx is a Word file.
Myproject.pptx is a PowerPoint file.
Myfriendslist.xlsx is an Excel file.
Essay.odt is a LibreOffice Writer document.
Photo.jpg is an image file.
What is a Folder?
A folder is like a container in which a collection of related files and subfolders are stored. A
sub-folder may contain one or more files and subfolders within. Folders do not occupy any disk
space. They point to specific file locations within the file system of the computer. There is no limit
on the number of folders or subfolders that can be created in Windows.
