Hello Kevin,<br>

Since the 24 hour filter is there, it will be a bit tricky to go back further than that. You can grab a list of items currently present in the sharepoint site, and loop it against a list of files present locally, to see if they are all accounted for. If one is not, then download it. This will require you to loop through every file one by one which can be a bit time consuming, but it should ensure that you dont miss any files.
