Sometimes you just need some files to be used or played in a specific order. For example, on (old) mp3 players, your songs will be played in alphabetical order, not the order in which you’ve put them in the map. This problem also occurs when you want to burn files in a specific order, most burning apps just sort them alphabetically. The quickest solution to this problem is to add numbers in front of the songs, listing them in the right order. Doing this by hand would take ages, but luckily Refile can do this for you in no time, for free. Yes, free, some people want $30 for their bulk renaming tools.
