M3U is the most used IPTV script among all IPTV users and it can be used on Smart TV, Smartphones, Android setup boxes, STB emulators, Roku and so forth.
How to edit an M3U file and create a favorites list
The M3U files can be edited with any text editor such as notepad because the files are text-based. You can simply open the downloaded M3U file with a notepad and delete the unwanted channels from the list and save the file on your computer. Then you can use this customized M3U file with your IPTV applications.
Why the channels are not categorized
The reason is that you are using a simple M3U URL or file. In order to have channels in groups and categorized, you must use M3U with options as your IPTV script.
The progressive IPTV providers give you a dashboard which you can download your M3U url, generate M3U with options url and reload your list to have channels categorized.
If you don’t have access to any dashboard system ask your IPTV provider for M3U with options url.
