Creating Empty Files from the Windows Command Line
Learn various methods to quickly create empty files using built-in Windows command-line tools, including type
, fsutil
, echo
, and PowerShell.
Creating an empty file is a common task in scripting, development, and system administration. While graphical interfaces allow for easy right-click creation, knowing how to do this efficiently from the command line in Windows can significantly boost your productivity. This article explores several robust methods, catering to different scenarios and preferences.
Method 1: Using type nul > filename.txt
This is one of the most straightforward and widely used methods. The type
command is typically used to display the contents of a text file. When combined with nul
, which is a special device file that discards all data written to it and returns an empty stream when read, it effectively creates an empty output. Redirecting this empty output to a new file creates an empty file.
type nul > emptyfile.txt
Creating an empty file using type nul
.
Method 2: Using fsutil file createnew filename.txt 0
The fsutil
command is a powerful utility for managing file system properties. Its createnew
subcommand allows you to create a file of a specified size. By setting the size to 0
, you can create an empty file. This method is particularly useful when you need to pre-allocate space or ensure a file exists with a specific size, even if that size is zero.
fsutil file createnew another_empty.log 0
Creating an empty file with fsutil
and specifying zero size.
fsutil
might require administrator privileges in some contexts or for certain file system operations. For simple empty file creation, type nul
is often sufficient.Method 3: Using echo.
or echo >
The echo
command is used to display messages or turn command-echoing on or off. When used with redirection, it can also create files. echo.
(note the dot) outputs an empty line, which when redirected, creates a file with a single newline character. If you want a truly zero-byte file, echo > filename.txt
works by redirecting an empty string.
echo. > file_with_newline.txt
echo > truly_empty.txt
Creating files using echo
. The first command creates a file with a newline, the second creates a zero-byte file.
Method 4: Using PowerShell
PowerShell offers more advanced and object-oriented ways to interact with the file system. The New-Item
cmdlet is the most direct way to create a new file. You can specify the item type as File
and provide the path. Alternatively, you can use Set-Content
with an empty string.
New-Item -Path "C:\temp\powershell_empty.txt" -ItemType File
Set-Content -Path "C:\temp\another_ps_empty.txt" -Value ""

and Set-Content

Decision flow for choosing a method to create an empty file.
1. Open Command Prompt or PowerShell
Press Win + R
, type cmd
or powershell
, and press Enter
.
2. Navigate to Desired Directory (Optional)
Use the cd
command (e.g., cd C:\Users\YourUser\Documents
) to go to the folder where you want to create the file. If you don't navigate, the file will be created in your current working directory.
3. Execute Your Chosen Command
Type one of the commands discussed above (e.g., type nul > mynewfile.txt
) and press Enter
.
4. Verify File Creation
Use dir
or ls
(in PowerShell) to list the files in the directory and confirm your new empty file exists. You can also check its size.
