Does anyone know how do I set the default program to open media files in Windows 7? On WinXP it was right click -> open with -> checkmark "set as default program for opening this type of file" -> double click program. I did the same thing on Windows 7 and it has absolutely no effect. I do NOT want to play music/movie files with Windows Media Player, yet every time I try to play any music file (.mp3, .wav, etc), it ALWAYS open with Win Media Player, even though I have clearly set the default program to open these files as something else... same thing applies to movies. Does anyone know what's going on here? @.@ Oh and a related question: can anyone tell me how to sort music files in windows explorer? For all other files there are tags that I can sort them by such as "file name", "date modified", "type", "size", etc, which is very convenient. However for music files it changes to "title", "contributing artist", and "album". I don't care about these information, I want to sort them by size, file type (in fact I don't even know what kind of file it is unless I right click and go to properties), and date modified. None of the view change functions seem to be able to provide these information. Thanks.
