As you can see I have uploaded two screenshots, in the first one I have just added the directory in which the files are as you can clearly see, still it is showing directory not found. In the second one I have added the command for no trailers, as I have no experience of working with cmd I'm sure I have put the --no-trailers in the wrong place, in that case, please guide me where to put it and if possible please send me the exact code or a screenshot. That will be really helpful.
PS - All files are mp4 only.
