  • what type of `file` are you trying to create? Or in other words what file extension? Like .txt .docx etc... – akasoggybunz Aug 01 '17 at 19:36

    Strange **I** get plenty of results with your [exact title in google](http://www.google.com/search?q=Creating+new+file+through+Windows+Powershell) Don't expect more from others than you are willing to do -1. –  Aug 01 '17 at 19:46

I'm guessing you're trying to create a text file?

New-Item c:\scripts\new_file.txt -type file

Where "C:\scripts\new_file.txt" is the fully qualified path including the file name and extension.

To create file using echo

echo some-text  > filename.txt

Example:

C:\>echo This is a sample text file > sample.txt
C:\>type sample.txt
This is a sample text file
C:\>

To create file using fsutil

fsutil file createnew filename number_of_bytes

Example:

fsutil file createnew sample2.txt 2000
File C:\sample2.txt is created
C:\data>dir
01/23/2016  09:34 PM     2,000 sample2.txt
C:\data>

Limitations

Fsutil can be used only by administrators. For non-admin users it throws up below error.

c:\>fsutil file /?

The FSUTIL utility requires that you have administrative privileges. c:>

Hope this helps!

    Please don't suggest the use of `echo` - an alias for the rarely needed `Write-Output` cmdlet - because it is a bad habit to promote in the PowerShell world. Newcomers need to be guided towards PowerShell's _implicit_ output model: `'some-text' > filename.txt`. If your code is meant to be `cmd.exe` code (it also works as that), please note the the question is tagged [tag:powershell]. – mklement0 Aug 02 '17 at 01:17

street smart (quick, dirty but works): (might change the file and add an invisible character which might cause the compiler to fail)

$null > file.txt
$null > file.html

Textbook method:

New-Item -path <path to the destination file> -type file

example:

New-Item -path "c:\" -type file -name "somefile.txt"

OR

ni file.xt -type file

absence of -path parameter means it creates it in the current working directory

ni filename.txt

Replace filename.txt with your file .

I found this the simplest answer to the question, and refer to other answers for more details.

    Quick thing to point out here is that `ni` is a default alias for the `New-Item` command. Alias information for a specific command can be view via the `gal -definition` command, e.g. `gal -definition New-Item`. – Dillon Aug 07 '20 at 14:43

    I really liked this answer. Also ni (New-Item) creates the file with UTF-8 encoding and echo creates it with ucs-2 le bom(UTF-16) encoding. Unless you change the encoding, the files created with echo will be twice the size. – Des Sep 15 '20 at 09:38
  • This is easiest. Note that when running this, my powershell asked for type, I put in `file` – mikey Nov 09 '20 at 21:44

Here is another way to create a blank text file in Powershell which allows you to specify the encoding.

First example

For a blank text file:

Out-File C:\filename.txt -encoding ascii

Without -encoding ascii, Powershell defaults to Unicode. You must specify ascii if you want it to be readable or editable by another source.

Overwriting the file with new text:

"Some Text on first line" | Out-File C:\filename1.txt -encoding ascii

This replaces whatever text is in filename.txt with Some Text on first line.

Appending text to the current file contents:

"Some More Text after the old text" | Out-File C:\filename1.txt -encoding ascii -Append

Specifying -Append leaves the current contents of filename.txt alone and adds Some More Text after the old text to the end of the file, leaving the current content intact.

As many have already pointed out, you can create files with the New-File command.
This command has a default alias set to ni but if you're used to unix commands you can create your own custom command easily.

Create a touch command to act as New-File like this:

Set-Alias -Name touch -Value New-Item

This new alias will allow you to create new files like so:

touch filename.txt

This would make these 3 commands equivalent:

New-Item filename.txt
ni filename.txt
touch filename.txt

Keep in mind that for this to be persistent, you should add the alias to your powershell profile. To get it's location simply run $profile on ps. If you want to edit it directly, run code $profile (for VSCode), vim $profile (for vim) or whatever.

Another way to do it (method I like)

New-Item -ItemType file -Value 'This is just a test file' -Path C:\Users\Rick\Desktop\test.txt

Source: New-Item

Use the New-item cmdlet and your new file name.

New-item <filename>

Example:

New-item My_newFile.txt

New-Item file.js -ItemType File -Value "some content"  # UTF-8

"some content" | Out-File main.js -Encoding utf8       # UTF-8-BOM

echo "some content" > file.js                          # UCS-2 LE BOM
