Exclude Directories

Rationale

Not all directories in your root folder need to visible. Not all directories in your root folder need to show up in search results.

On my current project I have excluded these folders: .idea, coverage, log, and tmp.

Note: you can always see all directories in the root folder by choosing the Project scope.

Mechanism

Right click on a folder and select Mark Directory As > Excluded.

You can see the total effect of your exclusions go to
