This is what you'll need for the default download location that you're looking for. Youtube-dl also allows use of a configuration file - a file that can be used to configure the switches you most frequently use so the program can pull them from there instead, saving you from having to explicitly call them each time you run it. For all of the variables that can be used in a filename, have a look at the youtube-dl documentation here. In this example, it will output the title of the original downloaded video followed by the file extension, which is my personal preference. Youtube-dl -o '%USERPROFILE%\Desktop\%(title)s-%(id)s.%(ext)s' Note that -o has a dual function in that it also sets a template for how your output files will be named, using variables.
Output on youtube-dl is handled with the -output or -o switch pass it as an option, followed by the destination you want to save your downloads to: You need to use the -o switch with the Configuration file
