    1. Filter your files so only releveant data is showing. For example, only XLSX file (or CSV or whatever they are), and only the folder structures you want - root\presentation for example. Call this "File LIst"
    2. Create a reference to that query. Call this "Latest File Name"
    3. Use the Group By function in Power query to group by folder and show the maxium file date.
    4. Create a reference to the File LIst query and call it "Final Files"
    5. Merge Final Files with "Latest File Name" joining the folder name and the file date. Use Inner Join
    6. Now you should only have a list of the last file in each of the relevant folders.
    7. Press Combine.
