## Overview
We can check if a file exists in Ruby by using the **`exists?()` method** of the File class.
This method returns a Boolean value signifying if the file exists or not.
## Syntax
```ruby
File.exists?(file_name)
```
## Parameters
**`file_name`**: This is the name of the file whose existence we want to check.
## Return value
This method returns a Boolean value. It returns `true` if the file exists, and `false` if it doesn't.
## Code example

# Create file names
fn1 = "main.rb"
fn2 = "test.txt"
fn3 = "fake.txt"
fn4 = "empty.txt"

# Check if the files exist
puts File.exists?(fn1)
puts File.exists?(fn2)
puts File.exists?(fn3)
puts File.exists?(fn4)

## Explanation
* **Lines 2 to 5**: We create some file names, of both files that exist and those that do not.
* **Lines 8 to 11**: We check if the files exist. Then, we print the results to the console.
