Serviio

Hello, is this normal? I jst set up serviio on my father's pc. On samsung smart TV I open photos app, go to serviio but the folders are not like in a pc! Seems like all folders are in a long list and there is no tree structure. This is pretty confusing and it's hard to find anything when folder names are dates. Is this just normal for DLNA protocol or for Samsung TVs? Or can this be somehow changed and setup somewhere in Serviio console? (just web console works for me). I have shared to folders d:\fotky and f:\fotky. They contain quite deep structure of subfolders

What is your setting on the Presentation tab of Serviio Console for Folders (ensure it is "Display Category").

Hm so I found it. What is the difference between display category and display content only?
And what is the purpose of the Albums view please? Maybe I am just lazy to search for some tutorials :-]
