In this little article I describe how to use the cmdlet Test-Path to check if a folder exists. Type Get-Help Test-Path for built-in information. I also briefly demonstrate how to use the. NET class method Exists from the class System. Remember that you need single or double quotes around the path if it contains a space.
To explicitly make sure it's a directory and not a file, use the -PathType parameter which accepts the following values:. In a script, you would typically use it in an if statement. To negate and check if the folder or file does not exist, use either "! Also remember that if the path or folder name contains a space, you need to surround the entire path in quotes. Single quotes or double quotes will work the same if there are no "expandable" parts in the path or folder name, but the slightly safer choice is single quotes.
This is what PowerShell defaults to when you auto-complete names with tab at the prompt. You should also be made aware of the parameter -LiteralPath to Test-Path, that you can see in the second example above. This also works if your file contains characters like brackets that causes the -Path parameter to expand the path since it supports wildcard syntax by default.
Use -LiteralPath if you don't need expansion from -Path as it's the safer choice for oddly named files. To create a directory if it does not exist, this is a very robust example of how you might want to handle it.
Adapt to suit your needs.
Working with Files and Folders
A small "trick" to see the possible enumeration values for -PathType is to use one that doesn't exist, like this:. You can also use the Exists method from the. NET System. Directory class, which requires a full path:. In PowerShell, the namespace "System" doesn't have to be typed in explicitly, so you can omit it. Jump to: navigationsearch.

We can use the New-Item PowerShell cmdlet to create a folder.
Now we will check how to create a folder if not exists in PowerShell. The PowerShell command will check if a folder already exists or not. If the folder does not exist then it will create a folder.
You can see the below fig since the folder already exists, it will just display the message as Folder already exists. If the folder or directory does not exists, the PowerShell cmd will create directory if not exists.

For example, you can use this cmdlet to get the value of the LastAccessTime property of a file object. You can also use this cmdlet to view registry entries and their values.
The result is piped to the Format-List cmdlet to display the output as a list. This command displays the value name and data of each of the registry entries contained in the "CurrentVersion" registry subkey. A drive with that name and mapping is available in PowerShell by default. Alternatively, the path to this registry subkey can be specified by using the following alternative path that begins with the provider name followed by two colons:.
This command gets the value name and data of the "ProgramFilesDir" registry entry in the "CurrentVersion" registry subkey. The Path specifies the subkey and the Name parameter specifies the value name of the entry.
Using PowerShell – Create a folder if not exists
This command gets the value names and data of the registry entries in the "PowerShellEngine" registry key. The results are shown in the following sample output. 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.
Specifies, as a string array, an item or items that this cmdlet excludes in the operation. The value of this parameter qualifies the Path parameter. Wildcard characters are permitted. Specifies a filter to qualify the Path parameter. The FileSystem provider is the only installed PowerShell provider that supports the use of filters. Filters are more efficient than other parameters, because the provider applies them when the cmdlet gets the objects rather than having PowerShell filter the objects after they are retrieved.
Specifies, as a string array, an item or items that this cmdlet includes in the operation. Specifies a path to one or more locations. The value of LiteralPath is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences. Get-ItemProperty returns an object for each item property that it gets.
The object type depends on the object that is retrieved. For example, in a file system drive, it might return a file or folder. The Get-ItemProperty cmdlet is designed to work with the data exposed by any provider.
To list the providers available in your session, type Get-PSProvider. Skip to main content. Contents Exit focus mode.
Get-Item Property Module: Microsoft. Gets the properties of a specified item. Note This parameter is not supported by any providers installed with PowerShell. Specifies the name of the property or properties to retrieve. Specifies the path to the item or items.
Powershell: Get parent directory name from file or directory path
Is this page helpful?In this post, you will see various options for extracting folder name from given file or directory path. This is generally useful in many ways as you work more with file and folders. Let us proceed to see how we can achieve this. This operation might look simple if you just have one path and what you do if you have to do this for some 10, files paths?
Obviously a programmatic approach is destination. The GetDirectoryName method takes a path as input and returns the directory name. Alternative to this is using split-path cmdlet that comes with PowerShell.
Using this cmdlet is much better than GetDirectoryName method because this cmdlet provides several other features.

WP Admin.Navigating through Windows PowerShell drives and manipulating the items on them is similar to manipulating files and folders on Windows physical disk drives.
This section discusses how to deal with specific file and folder manipulation tasks using PowerShell. You can get all items directly within a folder by using Get-ChildItem. Add the optional Force parameter to display hidden or system items. For example, this command displays the direct contents of Windows PowerShell Drive C which is the same as the Windows physical drive C :.
The command lists only the directly contained items, much like using Cmd. In order to show contained items, you need to specify the -Recurse parameter as well. This can take an extremely long time to complete. To list everything on the C drive:. Get-ChildItem can filter items with its PathFilterIncludeand Exclude parameters, but those are typically based only on name.
You can perform complex filtering based on other properties of items by using Where-Object. The following command finds all executables within the Program Files folder that were last modified after October 1, and which are neither smaller than 1 megabyte nor larger than 10 megabytes:.
Copying is done with Copy-Item. If the destination file already exists, the copy attempt fails. To overwrite a pre-existing destination, use the Force parameter:. Folder copying works the same way. You can also copy a selection of items. The following command copies all. You can still use other tools to perform file system copies. For example, you can use the Windows Script Host Scripting. Creating new items works the same on all Windows PowerShell providers. If a Windows PowerShell provider has more than one type of item—for example, the FileSystem Windows PowerShell provider distinguishes between directories and files—you need to specify the item type.
When using the Force switch with the New-Item command to create a folder, and the folder already exists, it won't overwrite or replace the folder. It will simply return the existing folder object.
However, if you use New-Item -Force on a file that already exists, the file will be completely overwritten.
You can remove contained items using Remove-Itembut you will be prompted to confirm the removal if the item contains anything else. If you do not want to be prompted for each contained item, specify the Recurse parameter:.
You can also map a local folder, using the New-PSDrive command. The following command creates a local drive P: rooted in the local Program Files directory, visible only from the PowerShell session:. Just as with network drives, drives mapped within Windows PowerShell are immediately visible to the Windows PowerShell shell. In order to create a mapped drive visible from File Explorer, the parameter -Persist is needed. However, only remote paths can be used with Persist.
One of the more common storage formats for text data is in a file with separate lines treated as distinct data elements. The Get-Content cmdlet can be used to read an entire file in one step, as shown here:. Get-Content already treats the data read from the file as an array, with one element per line of file content.Powershell: Check If File Exists
You can confirm this by checking the Length of the returned content:. This command is most useful for getting lists of information into Windows PowerShell directly.In this little article I describe how to use the cmdlet Test-Path to check if a file exists - as well as a. Type Get-Help Test-Path for more information, possibly with the "-online" switch. I also quickly demonstrate the.
NET class method Exists from the System. File class. I also demonstrate how to create a new file if one does not currently exist and show how to handle failures to create the file gracefully. The official Microsoft online documentation is here at this link.
Be aware that you need quotes if the path contains spaces, parentheses - and possibly other characters I can't think of now. PowerShell automatically adds quotes when you tab complete. To explicitly make sure it's a file and not a directory, use the -PathType parameter which has the following possible values:. In a script, you would typically use it in an if statement.
To negate and check if the folder or file does not exist, use either "! Also remember that if the path or file name contains a space, you need to surround the entire path in quotes.
Single quotes or double quotes will work the same if there are no "expandable" parts in the path or file name, but the slightly safer choice is single quotes.
This is what PowerShell defaults to when you auto-complete names with tab at the prompt. You should also be made aware of the difference between -Path and -LiteralPath. The latter will take the path literally, as the name indicates, while the former supports wildcard syntax. This is often discovered by accident when someone encounters a file with uneven brackets in it, because it's part of the same syntax -like uses, as in [a-f] for one hex digit.
This will cause error messages, at least on earlier versions of PowerShell, when using -Path. When listing directory structures from one root directory, use -LiteralPath. And unless you need wildcard support, it's the safer choice. I figured it's good to demonstrate what's likely considered the most proper script usage way first.
Set-Content or Out-File. Seeing is believing often sometimes wrongly, but that's another storyso here's a screen dump from PowerShell ISE running this example stored in a. A small "trick" to see the possible enumeration values for -PathType is to use one that doesn't exist, like this:. One thing to be aware of, is that with this method, you need a full path. To check if a file is in the current directory with the IO.
File Exists method, you can use something like this, where you would typically use a variable with the file name in place of the here hard-coded "test. Jump to: navigationsearch.
