Abnormally high OneLake Storage

[willmasse]

We just started a Fabric trial, and only have a handful of csv files in OneLake storage. In the Fabric Capacity Metrics app we already see almost a GB of storage, I would expect to be at a few hundred MB at this point. Is there any way to investigate this further? There isn't any drilldown in this app to see where that storage is coming from.

Don't forget Delta Lake and TimeTravel.  You may have multiple versions of your source data in Fabric.
