  <button className='btn'>Upload</button>
</ReactFileReader>

When base64 is true, React File Reader returns a JS Object including both the base64 files and the HTML5 FileList. You can access their values at Object.base64 or Object.fileList

```javascript
handleFiles = (files) => {
  console.log(files.base64)
}

<ReactFileReader fileTypes={[".csv",".zip"]} base64={true} multipleFiles={true} handleFiles={this.handleFiles}>
  <button className='btn'>Upload</button>
</ReactFileReader>
```

#### Response

###### multipleFiles={true}
```
["data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA", "data:image/png;base64,i..."]
```

###### multipleFiles={false}
```
  "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAA..."
```

###### Access HTML5 FileList with base64={true}
```
handleFiles = (files) => {
  console.log(files.fileList)
}
```
