Key Moments - 2 Insights

What happens if the file does not exist when Remove-Item runs?

If the file does not exist, Remove-Item throws an error and stops unless you use -ErrorAction to handle it. In the execution table, step 1 would show 'File does not exist' and the script would not proceed to removal.

Does Remove-Item delete folders as well as files?

Yes, Remove-Item can delete both files and folders. For folders, you may need to add -Recurse to delete contents. This is not shown in the simple example but is important for folders.
