File Dropper Event microflow

I am using File Dropper and suppose if I attached 3 files then Event Microflow is getting called 3 times but I want it to be called only once. I kept Before Commit Microflow and it is getting called three times which is not required.   Please help on how to fix this.

This is expected behaviour.

The microflow has a single file object as the parameter and processing is handled on an individual file level. If you uploaded 3 files, the microflow will be called 3 times with a different object passed each time.

What are you trying to do that needs a microflow to only be executed once? There may be a way to refactor your logic to achieve this.
