Determining which FCP file corresponds to a project

So I want to take a copy of my FCP project from my videographer's iMac so I can make edits on my own.. There is a folder containing several FCP project files that add up to 700GB and we don't know which one corresponds to my project. The filenames are just a series of numbers. I don't want to transfer 700GB of unrelated project files to my HD. My project is only about 130GB. How to determine which one is mine? Thanks!

Make a new library. Drag the project into the new library event. Make sure the new library is set to store media inside the library. Use the consolidate function to copy the clips used in the project into the new library.
