Looking for image viewing app which can browse folders

[Android Central Question]

Hi,

I wonder if you know of any app which can
- browse folders and subfolders. Today the apps mostly show all pictures togeter, but I need to browse folders
- once you pick the image from the folder it displays it fullscreen
- once displayed fullscreen swiping left and right shows prev/next images in that directory. Still fullscreen.
- the app is not paid. I'm happy to pay, but the device does not have google account so I can't use google play. I can download the apk files from android but not for paid apps.

For example f-stop can do what I need, but it's paid so can't get it without google play / google account.

Many thanks

FOTO Gallery may do it (I'm not sure about swiping to get to the next image).
