Power Query load new .dat files to existing query.
Hello,
I have a network drive that has new .dat files added each week with new and existing data. what im looking to do is make my refreash faster. Right now when i refresh it looks at every file within the Drive and creats the query. this take 30-40 minutes each time.
is there a way to create a query that adds new dtata each week to the existing query? instead of starting from the very first file again?
Hopefuly im explaning this right im fairly new to power BI.

Hi Rookzie ,
When importing data via Power BI Desktop, it'll always refresh all required data that is needed for your data model. However, what you can do is set an incremental refresh policy and publish the model to a workspace. What it'll do is create partitions for you and only refresh the latest x amount based on your policy.
You may find more info on that here:

Hope that helps!
