The Flat Browsing mode is a special browsing mode when S3 Browser displays the files 'as is', in raw form without breaking the path to folders, exactly as they are stored on Amazon S3, and you may specify any custom prefixes.
In this mode you may search across entire bucket for files which names start with the specific prefix. For example the prefix: folder1/subfolder2/file_0 will return all files starting with file_0 located in folder1 and subfolder1
