# Resource Organization

## File Assignment

Resources are assigned to <mark style="color:$primary;">**Terraform**</mark> files based on:

* **Default Assignment:** New resources go to <mark style="color:$primary;">**`main.tf`**</mark> by default.
* **Automatic Separation:** Variables go to <mark style="color:$primary;">**`variables.tf`**</mark>, outputs to <mark style="color:$primary;">**`outputs.tf`**</mark>, etc.
* **Manual Assignment:** You can assign resources to different files. To do so:
  * Right-click the resource in the diagram.
  * Select **"Move to file"**.
  * Choose an existing file or create a new one.
