Inside the project folder there are three main folders:
Assets is where I store all footage, audio and graphics.

Edits is where all the open edits are kept.

Renders is where all the exports are kept.

Audio contains all audio for the project. This includes recorded dialogue, voiceovers, music and SFX like foley.

Graphics contains text and certain effects such as the flare of a gunshot.

Rushes contains all of the visual footage. Every take and shot that has been recording from the start of production to the end.
