Description

If the path length is longer than 256 character, youtube-dl will trigger ERROR: unable to open for writing: [Errno 2] No such file or directory

It took me more than a half hour to understand that it was the problem. I was trying to fix my scripts and got the error, I thought something else was wrong but in the end it was just youtube-dl not being explicit about the error, it would be nice if it could at least say to check for the path length.

To reproduce the problem:

Using this video: https://youtube.com/watch?v=kn4AR7CbluE named "I THOUGHT I wanted this... - Razer Blade Pro 17 Review"

Using the output format --output "%%(title)s - %%(uploader)s - %%(upload_date)s/%%(title)s - %%(uploader)s - %%(upload_date)s.%%(ext)s"

If youtube-dl is ran in a path with more than 77 characters the error is triggered

So:

Broken : C:\abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuv

Trigger: ERROR: unable to open for writing: [Errno 2] No such file or directory: 'I THOUGHT I wanted this... - Razer Blade Pro 17 Review - Linus Tech Tips - 20191119\\I THOUGHT I wanted this... - Razer Blade Pro 17 Review - Linus Tech Tips - 20191119.f313.webm.part'

Working : C:\abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstu

@dstftw Can you stop closing my issues without even reading them?

You already closed my Feature Request because you didn't understand what I was asking, can you at least read a major bug report for Windows users, it's not even a duplicate.

Also please link the issues of which this is a duplicate.

Stop posting duplicates and ambiguously interpretable issues and I won't close them.
youtube-dl reports exactly what it receives from the underlying API. There is no special telepathy to know what is the real reason - checking length is not a reliable way since max path may be disabled in registry. There is already general purpose issue on long paths exists, bother to use search.
