# Resource Files

Resource files are the files your web application needs to use.

There are two formats of resource files.

Format 1 is for the traditional vanilla JavaScript development. You can find the files in the [SDK installer](https://www.dynamsoft.com/web-twain/downloads/) or official samples' zip files.

```
