Description of your issue, suggested solution and other information

When the combination of path and filename (of description or json) is too long, it doesn't download. The filename of the video seems will be trimmed so it alone doesn't cause problem (I can download without --write-description switch).

I suspect that's because the description file and json file has longer extension, and Youtube-dl doesn't check them.

Try youtube-dl https://twitter.com/HurstPoliceDept/st atus/986633953099608064 --write-description -v in a long enough path (in my case, it's merely C:\Users\Administrator\Desktop) to reproduce.
