I'm posting this on behalf of another user, who emailed our info email with this question, paraphrased below:   I have a query question regarding tables in Synapse. I started downloading some data for analysis and but my computer lost internet connection so I wasn?t able to download all of the fileHandles I want. I?d like to be able to resume downloading but exclude the fileHandleIds that I?ve already downloaded. I?m using the Python client. How can I do this efficiently?"   Any Python experts available to help out? Thanks!
