First off the way I download mp4 files is by using a free addon for my firefox browser called "Video DownloadHelper" which I have been using for years now. Next I have a place where I download all new downloads to when using this addon. I have a folder in the videos section where I download all downloads from this addon. Once I have the downloads for a specific TV Show done I rename them by season with a free program called "Rename My TV Series" I have been using this program for a few years as well. Example: I just downloaded a TV show called "This Is Us" I now have all 6 seasons. I found them on a free streaming site and then I downloaded them. Once they had been downloaded I then changed the name of the files from random text to the actual TV show name with season number and episode number and episode title all in the file name. So the file name went from looking like this: This Is Us - s5 e1 Watch Free Site Name.mp4 To looking like this:This Is Us (...
