can i choose an option to always skipping hash code while start downloading
“hash code”? Did you mean the hash-check?
If that’s what you meant, BitComet doesn’t perform a hash-check when the download starts – there would be nothing to check, so no point.
BitComet does perform a hash check when a download is **RE-**started after being interrupted vs. being stopped. This is because the download is in an unknown state. Since the download is not sequential, corruption could occur anywhere. The best way to prevent this is not to interrupt tasks. Stop them or shut them down properly. If the interruption happens because of a crash, then it’s best to let the hash-check run and make sure your download is intact.
