Description
The New-Item
cmdlet creates a new item and sets its value. The types of items that can be created
depend on the location of the item. For example, in the file system, New-Item
creates files and
folders. In the registry, New-Item
creates registry keys and entries.
New-Item
can also set the value of the items that it creates. For example, when it creates a new
file, New-Item
can add initial content to the file.
Examples
Example 1: Create a file in the current directory
This command creates a text file that is named "testfile1.txt" in the current directory. The dot ('.') in the value of the Path parameter indicates the current directory. The quoted text that follows the Value parameter is added to the file as content.
New-Item -Path . -Name "testfile1.txt" -ItemType "file" -Value "This is a text string."
Example 2: Create a directory
This command creates a directory named "Logfiles" in the C:
drive. The ItemType parameter
specifies that the new item is a directory, not a file or other file system object.
New-Item -Path "c:\" -Name "logfiles" -ItemType "directory"
Example 3: Create a profile
This command creates a PowerShell profile in the path that is specified by the $profile
variable.
You can use profiles to customize PowerShell. $profile
is an automatic (built-in) variable that
stores the path and file name of the "CurrentUser/CurrentHost" profile. By default, the profile does
not exist, even though PowerShell stores a path and file name for it.
In this command, the $profile
variable represents the path of the file. ItemType parameter
specifies that the command creates a file. The Force parameter lets you create a file in the
profile path, even when the directories in the path do not exist.
After you create a profile, you can enter aliases, functions, and scripts in the profile to customize your shell.
For more information, see about_Automatic_Variables and about_Profiles.
New-Item -Path $profile -ItemType "file" -Force
Example 4: Create a directory in a different directory
This example creates a new Scripts directory in the "C:\PS-Test" directory.
The name of the new directory item, "Scripts", is included in the value of Path parameter, instead of being specified in the value of Name. As indicated by the syntax, either command form is valid.
New-Item -ItemType "directory" -Path "c:\ps-test\scripts"
Example 5: Create multiple files
This example creates files in two different directories. Because Path takes multiple strings, you can use it to create multiple items.
New-Item -ItemType "file" -Path "c:\ps-test\test.txt", "c:\ps-test\Logs\test.log"
Example 6: Use wildcards to create files in multiple directories
The New-Item
cmdlet supports wildcards in the Path parameter. The following command creates a
temp.txt
file in all of the directories specified by the wildcards in the Path parameter.
Get-ChildItem -Path C:\Temp\
Directory: C:\Temp
Mode LastWriteTime Length Name
---- ------------- ------ ----
d----- 5/15/2019 6:45 AM 1 One
d----- 5/15/2019 6:45 AM 1 Two
d----- 5/15/2019 6:45 AM 1 Three
New-Item -Path * -Name temp.txt -ItemType File | Select-Object FullName
FullName
--------
C:\Temp\One\temp.txt
C:\Temp\Three\temp.txt
C:\Temp\Two\temp.txt
The Get-ChildItem
cmdlet shows three directories under the C:\Temp
directory. Using wildcards
the New-Item
cmdlet creates a temp.txt
file in all of the directories under the current
directory. The New-Item
cmdlet outputs the items you created, which is piped to Select-Object
to verify the paths of the newly created files.
Example 7: Create a symbolic link to a file or folder
This example creates a symbolic link to the Notice.txt file in the current folder.
$link = New-Item -ItemType SymbolicLink -Path .\link -Target .\Notice.txt
$link | Select-Object LinkType, Target
LinkType Target
-------- ------
SymbolicLink {.\Notice.txt}
In this example, Target is an alias for the Value parameter. The target of the symbolic link can be a relative path. Prior to PowerShell v6.2, the target must be a fully-qualified path.
Caution
If you are creating a SymbolicLink to a folder on Windows, you must use a fully-qualified path. If you use a relative path, the link is created as a file-type link instead of a directory-type link.
Example 8: Use the -Force parameter to attempt to recreate folders
This example creates a folder with a file inside. Then, attempts to create the same folder using
-Force
. It will not overwrite the folder but simply return the existing folder object with the
file created intact.
PS> New-Item -Path .\TestFolder -ItemType Directory
PS> New-Item -Path .\TestFolder\TestFile.txt -ItemType File
PS> New-Item -Path .\TestFolder -ItemType Directory -Force
Directory: C:\
Mode LastWriteTime Length Name
---- ------------- ------ ----
d----- 5/1/2020 8:03 AM TestFolder
PS> Get-ChildItem .\TestFolder\
Directory: C:\TestFolder
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 5/1/2020 8:03 AM 0 TestFile.txt
Example 9: Use the -Force parameter to overwrite existing files
This example creates a file with a value and then recreates the file using -Force
. This overwrites
The existing file and it will lose it's content as you can see by the length property
PS> New-Item ./TestFile.txt -ItemType File -Value 'This is just a test file'
Directory: C:\Source\Test
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 5/1/2020 8:32 AM 24 TestFile.txt
New-Item ./TestFile.txt -ItemType File -Force
Directory: C:\Source\Test
Mode LastWriteTime Length Name
---- ------------- ------ ----
-a---- 5/1/2020 8:32 AM 0 TestFile.txt
Note
When using New-Item
with the -Force
switch to create registry keys, the command will behave
the same as when overwriting a file. If the registry key already exists, the key and all
properties and values will be overwritten with an empty registry key.
Parameters
-Confirm
Prompts you for confirmation before running the cmdlet.
Type: | SwitchParameter |
Aliases: | cf |
Position: | Named |
Default value: | False |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-Credential
Note
This parameter is not supported by any providers installed with PowerShell. To impersonate another
user or elevate your credentials when running this cmdlet, use Invoke-Command
.
Type: | PSCredential |
Position: | Named |
Default value: | Current user |
Required: | False |
Accept pipeline input: | True |
Accept wildcard characters: | False |
-Force
Forces this cmdlet to create an item that writes over an existing read-only item. Implementation varies from provider to provider. Even using the Force parameter, the cmdlet cannot override security restrictions.
Type: | SwitchParameter |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | False |
Accept wildcard characters: | False |
-ItemType
Specifies the provider-specified type of the new item. The available values of this parameter depend on the current provider you are using.
If your location is in a FileSystem
drive, the following values are allowed:
- File
- Directory
- SymbolicLink
- Junction
- HardLink
Note
Creating a SymbolicLink
type on Windows requires elevation as administrator. However, Windows 10
(build 14972 or newer) with Developer Mode enabled no longer requires elevation creating symbolic
links.
In a Certificate
drive, these are the values you can specify:
- Certificate Provider
- Certificate
- Store
- StoreLocation
For more information see about_Providers.
Type: | String |
Aliases: | Type |
Position: | Named |
Default value: | None |
Required: | False |
Accept pipeline input: | True |
Accept wildcard characters: | False |
-Name
Specifies the name of the new item. You can specify the name of the new item in the Name or Path parameter value, and you can specify the path of the new item in Name or Path value. Items names passed using the Name parameter are created relative to the value of the Path parameter.
Type: | String |
Position: | Named |
Default value: | None |

Accept wildcard characters: | False |
-Path
Specifies the path of the location of the new item. The default is the current location when Path is omitted. You can specify the name of the new item in Name, or include it in Path. Items names passed using the Name parameter are created relative to the value of the Path parameter.
For this cmdlet, the Path parameter works like the LiteralPath parameter of other cmdlets.
Wildcard characters are not interpreted. All characters are passed to the location's provider. The
provider may not support all characters. For example, you cannot create a filename that contains an
asterisk (*
) character.

Notes
New-Item
is designed to work with the data exposed by any provider. To list the providers
available in your session, type Get-PsProvider
. For more information, see about_Providers.
