Browse & Search By Folders?

[metal450]

I'm looking for an open-source alternative to Synology's Photos app; my use case is accessing a photo library hosted on a NAS from an Android device. I gave the Photonix Android app a try with the demo instance, but wasn't able to determine: is there any way to browse the "file structure" layout directly? And likewise, to have "Search" return photos based on terms in their pathname?

Specifically: Although I realize metadata tags are more versatile, I have a very large existing photo library that's organized via folder names. Thus it's essential to be able to navigate by folder, as well as search for terms that appear in pathnames. I don't think this is currently possible, but just thought I'd ask to be sure :)

Thanks in advance

I'm also looking for an application that allows to browse photos by folder. All my photos are already sorted by folder.
If this is implemented, I'll give Photonix another try
