Thank you! I remember that I added this because I got the error when trasncribing youtube.
As my research most OS have file name length limitation of 255, would 200 be safe?

I was not sure if there was any other reason for this limit besides the file name length.
Therefore if left some buffer.
If there is no other reason, then we just have to account for the additional characters added as timestamp (if that option is activated).
So I think 200 should be good.

Maybe we could also try to use
os.pathconf(path, 'PC_NAME_MAX'),
To strip the file name to a proper length.

Thanks. I think 200 would be safe 😊.
It would be good if I could use os.pathconf, but it seems to be a Unix only API : https://docs.python.org/3.8/library/os.html#os.fpathconf

Thanks for contribution, merge it!
