Does it work on Linux and windows?

Does it work on Linux and windows?

Linux - yes (I have Mint 18.3 64bit)
Windows - don't know (my last Windows Version was XP, I do not need or want Windows anymore)

but it should run in Windows, you must change the path to the youtube-dl executable file.

("/usr/local/bin/youtube-dl" in Linux)

Alright. I'll try it. :)
