[TYPO3-english] how to get folder from file collection

[Domi]

Hello,
I try to get the folder from a folder based file collection:

/** @var FileCollectionRepository $fileCollectionInstance */
$fileCollectionInstance = 
GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Resource\\FileCollectionRepository');
		
$fileCollectionItem = $fileCollectionInstance->findByUid($uid);

$folder = $fileCollectionItem-> ????

I can't find any possibility to get the folder from a 
FolderBasedFileCollection.

Thanks for ideas.

Dominic
