File facts for kids

File is a word with several different meanings, depending on what you are talking about. It can mean a way to store information, a tool you use, or even a line of people!

Let's explore some of the most common ways we use the word "file."

What is a Computer File?

A computer file is like a digital document or container that holds information on a computer or other electronic device. Think of it as a folder in your school bag, but instead of paper, it holds digital data. This data can be anything from a picture you took, a song you listen to, a video, a game, or a school report you typed.

Computer files are stored on things like hard drives, USB sticks, or in the cloud (online storage). Each file has a unique name and usually an extension (like .jpg for pictures, .mp3 for music, or .docx for documents). This extension helps the computer know what kind of information is inside the file and which program should open it.

Types of Computer Files

There are many different types of computer files, each designed for a specific purpose:

• Document files: These hold text, like essays, letters, or reports. Examples include files made with programs like Microsoft Word (ending in .doc or .docx) or plain text files (.txt).
• Image files: These store pictures and graphics. Common types are .jpg (for photos), .png (for images with transparent backgrounds), and .gif (for animated images).
• Audio files: These contain sounds, like songs, podcasts, or voice recordings. The most common type is .mp3.
• Video files: These store moving pictures and sound, like movies or home videos. Examples include .mp4 and .mov.
• Program files: These are the files that make software and apps work. When you install a game or a program, you are putting program files onto your computer.

How Do We Use Computer Files?

We use computer files every day!

• When you save your homework, you are creating a file.
• When you download a new song, you are getting an audio file.
• When you take a photo with your phone, it creates an image file.
• When you open an app, you are running program files.

Files help us organize and keep track of all the digital information we create and use.

What is a File Menu?

In many computer programs and apps, you'll see a File menu at the top of the screen. This menu is a list of commands that help you manage your files. Common options you'll find in a File menu include:

• New: To create a brand new file.
• Open: To open an existing file that you've saved before.
• Save: To save changes to the file you are currently working on.
• Save As: To save a copy of your file with a new name or in a different location.
• Print: To print your file onto paper.
• Exit/Quit: To close the program.

The File menu makes it easy to handle your digital work.

What is a File (Tool)?

A file can also be a hand tool used to smooth, shape, or remove small amounts of material from wood, metal, or plastic. It's a bit like sandpaper, but much stronger and more precise.

A file tool has many sharp teeth or ridges on its surface. When you rub the file against a material, these teeth scrape away tiny bits, making the surface smoother or changing its shape. Files come in different shapes and sizes, and with different levels of roughness (called "cuts") depending on what you need to do. For example, a rough file might be used to quickly remove a lot of material, while a fine file would be used for a very smooth finish.

Other Meanings of File

• Filing Cabinet: This is a piece of office furniture with drawers where you store paper documents, often organized in folders.
• Filing (Legal): In legal terms, "filing" means officially submitting documents to a court or government office. For example, a lawyer might "file a lawsuit."
• File (Chess): In the game of chess, a "file" is one of the eight vertical columns of squares on the chessboard. These are usually labeled with letters from 'a' to 'h'.
• File (Formation): In military terms, a "file" refers to a single column of soldiers standing one behind the other.
