#      
#  Overview
The **`File.delete()`** method in **Ruby** deletes the named files specified to it. It returns the number of names passed as arguments. If we try to delete an already deleted file, the method throws an error.

#  
#  Syntax
```ruby
File.delete(file_name)
```

#  
## Parameters
* **file_name**: This is the name of the file we want to delete.

## 
## Return value
The number of parameters passed to the `delete()` method is returned.

## 
## Example

# Get file names
fn1 = "main.rb"
fn2 = "test.txt"

# Delete files
puts File.delete("test.txt")
puts File.delete("main.rb")

## Explanation
* We create the file `test.txt` along with `main.rb`, and `main.rb` contains our application code.

* **Lines 2 to 3**: We obtain the names of our files.

* **Lines 6 to 7**: We delete the files using the `delete()` method.

> **Note**: Deleting an already deleted file results in an error. See the example below:


# Get file names
fn1 = "main.rb"
fn2 = "test.txt"

# Delete files
puts File.delete("test.txt")
puts File.delete("main.rb")

# Deleting the same file throws an error
puts File.delete("test.txt")
