If the purpose of this issue is a bug report, site support request or you are not completely sure provide the full verbose output as follows:

Add the -v flag to your command line you run youtube-dl with (youtube-dl -v <your command line>), copy the whole output and insert it here. It should look similar to one below (replace it with your log inserted between triple ```):

Description of your issue, suggested solution and other information

When I run youtube-dl with single quotes around the Output Template, it actually creates a folder with a quote in the folder name.

For this example, I ran this command:
youtube-dl --verbose --format best --no-progress --output 'wwwroot/downloads/%(title)s_%(resolution)s.%(ext)s' https://www.youtube.com/watch?v=C0DPdy98e4c
and it created path and file like this (notice the two single quotes):
/var/www/mywebsite/'wwwroot/downloads/TEST VIDEO_480x360.mp4'
but I wanted it to create a file like this:
/var/www/mywebsite/wwwroot/downloads/TEST VIDEO_480x360.mp4

I am running this on ubuntu from a website created with C# and .Net Core. The website runs youtube-dl using the .net feature "Process.Start()". If I copy/paste the same command directly into my terminal, it works fine and creates the file without any extra quotes. Even though it seems somehow related to .Net Core, I think youtube-dl should be smarter at parsing single and double quotes around the Output Template. If you have any tips for fixing this another way, I'd be happy to try it.

Here's my .Net Core code:

        StringBuilder sbOutput = new StringBuilder();
        StringBuilder sbError = new StringBuilder();

        using (Process process = new Process())
        {
            ProcessStartInfo psi = new ProcessStartInfo();
            psi.FileName = RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ? "youtube-dl.exe" : "youtube-dl";

            string QuoteMark = RuntimeInformation.IsOSPlatform(OSPlatform.Windows) ? "\"" : "'";
            psi.Arguments = String.Format("--verbose {0} {1} {2} {3}",
                "--format best",
                "--no-progress",
                "--output " + QuoteMark + "wwwroot/downloads/" + "%(title)s_%(resolution)s.%(ext)s" + QuoteMark,
                RequestedVideo);

            psi.CreateNoWindow = true;
            psi.UseShellExecute = false;
            psi.RedirectStandardError = true;
            psi.RedirectStandardOutput = true;
            process.StartInfo = psi;
            

            process.OutputDataReceived += new DataReceivedEventHandler((sender, e) =>
            {
                sbOutput.AppendLine(e.Data);
            });
            process.ErrorDataReceived += new DataReceivedEventHandler((sender, e) =>
            {
                sbError.AppendLine(e.Data);
            });

            sbOutput.AppendLine("Starting with this command:");
            sbOutput.AppendLine(psi.FileName + ' ' + psi.Arguments);
            sbOutput.AppendLine("------------------------------------");
            sbOutput.AppendLine();

            process.Start();

            // Asynchronously read the standard output of the spawned process. 
            // This raises OutputDataReceived events for each line of output.
            process.BeginOutputReadLine();
            process.BeginErrorReadLine();

            process.WaitForExit();
            process.Close();
        };

Nothing to do with youtube-dl. Most likely .NET Core process API does not support single quotes.

[Germs2004]

In case anyone else has the same problem calling youtube-dl from a C# program, my only known workaround is to remove the quotes from around the arguments and just ensure that the arguments have no spaces.
