# How Client Updates and Asset Sync Work

## What's New
This page explains, at a high level, how SWG Secura keeps your client and the server in step so you do not see missing text, odd visuals or mismatched item data.

## What gets updated on your client
| Asset type | What it controls |
|---|---|
| String tables (`.stf`) | Quest text, NPC dialogue, system messages, item tooltips |
| User interface (`ui/` and `ui-4k/`) | Layouts, HUD, button bars, fonts, 4K interface |
| Datatables and templates (`.iff`) | Skills, weapon stats, schematics, appearances, quest data |
| CRC tables | Checksums so client and server agree on object templates and quest IDs |

## How it reaches you
1. **Build**: source data is compiled on the development cluster.
2. **Stage**: finished files are collected for distribution.
3. **Download**: the SWG Secura launcher verifies your files and downloads anything new before you launch.

## FAQ and Known Details
- **Do I have to do anything?** Just start the game from the launcher.
- **Why does the launcher sometimes download files?** A feature or fix shipped with new client data.
