TYPO3 Core

Hello,

currently I don't see any possibility to reach the folder of a FolderBasedFileCollection.

 /**
 * @var \TYPO3\CMS\Core\Resource\FileCollectionRepository
 * @inject
 */
 protected $fileCollectionRepository;

(...)

 $fileCollectionItem = $this->fileCollectionRepository->findByUid($uid);
 $content = $fileCollectionItem->loadContents();

$content is always empty and $fileCollectionItem->toArray() doesn't display the folder either.

Is there any documentation out how to reach the FolderBasedFileCollection?

For StaticFileCollection I currently use

 $fileRepository = GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Resource\\FileRepository');
 $fileCollection = $fileRepository->findByRelation('sys_file_collection', 'files', $uid);
 foreach ($fileCollection as $item) {
   /** @var FileReference $item */
   $files[] = $item->toArray();
 }

But I'm unsure if this is correct, shouldn't work $fileCollection->loadContents() here as well?

Do I miss anything important for using the FAL FileCollections feature?

In xDebug I can see inside of my object all information, but no possibility to reach it through the given functions.

Regards,
Dominic
