Change skip existing criteria

[nckrdgrs]

Hello, I am not experience with this language, but how can I modify this in order to change the criteria of an existing file to skip to only consider if the file exists in a path? From my understanding it currently checks the file size and if it is equal then it would skip.

I plan to download videos from a discord channel then once they are downloaded, I plan to reduce the quality of the videos to save on disk space, therefore checking the file size would not work in my case.

Thank you
