Skip already downloaded files; resume progress

[nexxai]

I don't know how difficult it would be to do this, but here goes...

I'm attempting to download all of the videos from a particular Vimeo channel. I hit their internal rate limiter and so youtube-dl quit. After a day or so, I went to run the tool again, but instead of picking up where it left off, it started from the beginning again, downloading videos it had already downloaded.

Is there a way for it to check if a file already exists in the folder with that name and skip that particular download if it does?

If it makes a difference, I'm using the latest Windows client (2016.03.27).

It does by default.
Post the full output of youtube-dl when run with -v, i.e. add -v flag to your command line, copy the whole output and post it in the issue body wrapped in ``` for better formatting. It should look similar to this:

$ youtube-dl -v <your command line>

The output (including the first lines) contains important debugging information. Issues without the full output are often not reproducible and therefore do not get solved in short order, if ever.
