# 2D Editor: External

Mission Editor provides majority of tools required for designing a mission, but finishing touches are usually made outside of it. Briefings, custom scripts, multiplayer settings or final packing are only handled by separate files programs.

### Mission Folder

#### Folder Name

Missions are stored as folders with name composed of mission name set in Save window and world name:

```
missionName.worldName
```

Examples:

```
TopGun.abel
SpyGame.Chernarus
Domino.ProvingGrounds_PMC
This.is.Sparta.Altis
```

World names match classes present in *CfgWorlds*.

#### Folder Directory

You can find all missions in your [Profile](../topics/Profile.md) directory.

Single player missions are located in *Missions* folder, multiplayer missions can be found in *MPMissions* folder in same directory.

#### Subfolders

Within the mission folder, you can create as many subfolders as desired. As paths in mission are relative, you can refer to such subfolder using:

```
\subFolderName\desiredFile.sqf
```

### Files

#### Mission.sqm

*Main article: [Mission.sqm](../topics/Mission.sqm.md)*

#### Description.ext

*Main article: [Description.ext](../topics/Description.ext.md)*

#### Scripts

*Main article: [Script File](../topics/Script_File.md)*

External script files are executed by filename, so they can have any filename the author chooses. There are however several special [Event Scripts](../topics/Event_Scripts.md) that are automatically executed by the game engine at certain times during the mission.

#### FSM

*Main article: [FSM](../topics/FSM.md)*

#### Overview.html

*Main article: [Overview.html](../topics/Overview.html.md)*

The overview.html contains simple mission description and picture visible in main menu mission selection.

#### Briefing.html

*Main article: [Briefing.html](../topics/Briefing.html.md)*

File loaded automatically when the mission begins, providing mission plan and notes.

The briefing is broken into 4 main sections:

- Notes
- Plan
- Objectives
- Endings

To preview your briefing whilst in the editor, hold SHIFT while clicking 'Preview'.

Since Arma 2, briefing.html is only used for the debriefing text. For more information see Arma 2 Briefing creation.
