Design a batch rename rule for my files

Designs one batch rename rule from sample file names, with a preview step and an undo plan before anything is renamed.

Task: Design one rename rule for the files below and write the PowerShell command that applies it. Context: I want the files named like [target pattern, for example 2026-03-12_invoice_acme.pdf]. The folder is [folder path]. I have about [number] files, and I am [new or comfortable] with PowerShell. Rules: - Explain in plain words what the command does before I run it. - Make the first version a preview that only prints the old and new names and changes nothing. - Warn me about anything destructive or hard to undo, such as two files ending up with the same name, and say how to avoid it. - Describe how to undo the rename, and tell me to try it on a copy of five files first. - Say when you are unsure how a command behaves in my setup and what I should verify. Result: The rule in one sentence, the preview command, the real command, and the undo steps in at most three lines. Material: [paste 10 to 20 current file names, one per line, here]
