I’ve left the company, but my old manager still sends me “one quick question”

On Wednesday morning, a message from my former manager arrived: “Where did we put the spring catalogue files?”

I left three weeks ago. Before leaving, I made a folder index and spent two afternoons handing work over. I answered the first message because I knew the file location immediately. Since then, there have been questions about print contacts, naming conventions and how to reopen an old project.

I’ve started a new job. The questions arrive while I’m learning that job, and even a short answer pulls me back into remembering the old one. I like my former colleagues and don’t want to be difficult. I also don’t want every answer to become the starting point for another question.

How would you close this off? Should I send one final pointer to the handover material, stop replying, or discuss a separate support arrangement if they need more than they expected?
