Unknown file type – FileBrowserGO: File Manager Review

So I downloaded this app so I can transfer pictures and files between apps and for some reason, some of my image files are of unknown type but images in other folders are perfectly fine and show that they are normal and they work. Out of like 6 folders like half of my images are an unknown type which is strange because in other file apps they show as images. Also, I wish there was access to Google photos.
