Listing files and folders with TYPO3 extbase fluid? - typo3

Question

I have files array like
'file1.pdf',
'file2.pdf',
'file3.JPG',
'Folder1/file1.pdf',
'Folder1/Subfolder1/Subfolder-file1.txt',
'Folder2/text.txt',
'Folder2/file2.pdf'
For get list of files and folder I use following fluid
<f:for each="{files}" as="userFile">
<f:if condition="{userFile -> myext:explode(delimiter:'/') -> f:count()} == 1">
<f:then>
{userFile}<br />
</f:then>
<f:else>
<div class="folder">
<f:for each="{userFile -> myext:explode(delimiter:'/')}" as="segment" iteration="itemIteration">
<f:if condition="{itemIteration.isFirst}">
<f:then>{segment}</f:then>
<f:else>{segment}<br /></f:else>
</f:if>
</f:for>
</div>
</f:else>
</f:if>
</f:for>
I'm using my own explode view helper
And I get only list files and folders
file1.pdf
file2.pdf
file3.JPG
<div class="folder">Folder1</div>
file1.pdf
<div class="folder">Folder1</div>
<a href="">Subfolder1
Subfolder-file1.txt
<div class="folder">Folder2</div>
text.txt
<div class="folder">Folder2</div>
file2.pdf
How I can get listing like with fluid?
file1.pdf
file2.pdf
file3.JPG
<div class="folder">Folder1</div>
file1.pdf
Subfolder-file1.txt
Subfolder-file1.txt
<div class="folder">Folder2</div>
text.txt
file2.pdf
Is it possible?

In your Extbase Controller you can use the TYPO3\CMS\Core\Resource\ResourceFactory to get folders:
$resourceFactory = \TYPO3\CMS\Core\Resource\ResourceFactory::getInstance();
// Format [ID OF STORAGE]:[FOLDER]
$folder = $resourceFactory->getFolderObjectFromCombinedIdentifier('1:my/directory/to/scan');
$this->view->assign('folder', $folder);
Now you can use folowing partial in your fluid to walk the folders:
Partial/FolderRecusive.html
<f:for each="{folder.files}" as="file">
<a href={file.publicUrl}>{file.name}</a>
</f:for>
<f:for each={folder.subFolders} as="subFolder">
<f:if condition="{subFolder.files -> f:count()} > 0 OR {subFolder.subFolders -> f:count()} > 0">
<div class="folder">{subFolder.name}</div>
<f:render partial="FolderRecursive" arguments="{folder:subFolder}" />
</f:if>
</f:for>
In your Template put something like this to display the folders:
<f:render partial="FolderRecursive" arguments="{folder:folder}" />
