OneClickPlay
by PoPo Software

  This fast and tiny utility scans, creates and launches a randomized playlist (OneClickPlay.m3u) of all MP3, WMA and MID files found in the folder it was installed (copied) in and all subfolders.
You can scan for any audio files by using switches. This will create a OneClickPlay.ini file. Once this file is created you don't have to use switches again. Should you want to make changes again, just use the switches or edit OneClickPlay.ini. All music files in the generated playlist will be played by the player (Winamp etc.) associated with M3U playlists. OneClickPlay is especially suitable for users whose music folder's content changes often.
Version 2.0 is completely rewritten in C++, no longer needs extra libraries and is even smaller. It offers several new switches for options such as launching only one randomly selected file (useful for playing random videos with the default player for example), excluding subfolders, runnig hidden, running in High priority mode and more. It also offers an improved graphical user interface featuring 'files found' and 'seconds elapsed' counters.
