  There are four columns: File, Size, Type and Last Modified that contain information about file name, size, type and date of the last modification. You can click on any column header to sort files by the selected criterion.

Additional information:

You probably noticed that there is a Current Path text-box. It displays the current path when you go down into the folders. It can also be used to quickly navigate to a specific path. For example if you are in Folder1/subfolder1/subsubfolder2 and need to jump to the root directory, you can just type / and press Enter.

You can also use the Up button to browse the parent directory.
