1. youtube-dl.exe https://www.youtube.com/watch?v=XSdWHeSf86U -F --write-pages --restrict-filenames -v
2. try to open the dash manifest from explorer.exe << Important
3. Windows throws error The filename or extension is too long

Reproduces 100% of the time on Windows 8.1 (didn't test other versions)

That is the problem of software you are using to open it.

That is the problem of software you are using to open it.

Well no because anything on the system that tries to read it or even delete the file results in error, maybe a bug specific to my version of Windows(8.1 x64)

[sheddup]

The whole path was too long, Windows limitation or something.

[dstftw]

Again: that is the problem of software you are using. If del can't work with paths longer than MAX_PATH it's not a youtube-dl's problem. explorer.exe works with such paths just fine.
