PowerShell:
Checking if a directory exists

How to:

PowerShell offers a straightforward way to check for the presence of a directory using the Test-Path cmdlet. This cmdlet returns a Boolean value indicating whether the specified path exists. Here’s how you can use it:

# Check if a directory exists
$directoryPath = "C:\ExamplePath"
$directoryExists = Test-Path -Path $directoryPath
Write-Output "Does the directory exist? $directoryExists"

Sample output for a directory that exists:

Does the directory exist? True

And for a directory that does not exist:

Does the directory exist? False

For more complex scripts, especially those interacting with network shares or cloud storage, you might need additional checks or functionality not directly available through Test-Path. In such cases, utilizing third-party PowerShell modules or libraries may be beneficial, though most routine tasks can be accomplished with PowerShell’s built-in cmdlets. As of my last knowledge update, there hasn’t been a widely adopted third-party library specifically for checking directory existence beyond what Test-Path provides, mainly because Test-Path itself is both robust and efficient for this purpose.
