An M3U file is a plain text multimedia playlist. A playlist specifies song name and information, and the location of the multimedia file. M3U files are commonly used by multimedia players. M3U files are encoded in plain text Windows-1252 format using the Latin-1 character set. They may be edited by a common text editor.
HTTP Live Streaming services use the M3U playlist format to specify song order on Apple devices running iOS. The M3U file specifies the media file directory location and filename on a variety of formats, including OS X, iOS, Linux, Unix, and Windows.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .M3U file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .M3U file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .M3U file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .M3U extension. Directly on this website you can find a solution of the most common problem with the .M3U file – that you do not have on your computer the appropriate program to open the file.
