I'm not very experienced with PowerShell, but I've been using a script to resolve a file preview problem caused by a recent Windows update. While the script works perfectly, it doesn't seem to affect the subfolders within the directory I run it on. For example, I have a script like this:
Unblock-File -Path "C:Usersadmindownloads*.pdf"
This only works for files directly in my downloads folder, but if there are any subfolders (such as those created from an extracted zip file), the script doesn't apply to them. I need to adjust the command to ensure it applies to all subfolders as well. How can I change my script accordingly? Thanks!

You could also try using:
```powershell
ls -r | % { ** $_ }
```
Just replace `**` with your unblock command. But keep in mind, while this shorthand works, detailed scripts are usually better for clarity.
If you want to see if your script has a recursion parameter, check the list of parameters at the top of your script. Sometimes it might have built-in ways to process subdirectories without a lot of manual adjustments.
You can modify your command to include recursion by using the `Get-ChildItem` cmdlet like this:
```powershell
Get-ChildItem -Recurse -Path "C:Usersadmindownloads" | Unblock-File
```
This command will go through all subfolders and unblock the PDF files. It's really useful for batch processing! Just make sure to add error handling if there are any files that can't be unblocked.
