```
    Construct an extension file filter by giving the extension to check after.
    
    Parameters:
    
    extension - The comma-separated list of file extensions
    
    defaultExtension - The default extension
    
    description - A short textual description of the file type

  - updateAllFormatsImporter
```
public static void updateAllFormatsImporter()
```
    Updates the AllFormatsImporter that is contained in the importers list. If you do not use the importers variable directly, you don’t need to call this.
    Updating the AllFormatsImporter is required when plugins add new importers that support new file extensions. The old AllFormatsImporter doesn’t include the new extensions and thus will not display these files.
