How can I do a COMMIT without first doing an initial checkout?

I have a repository already online, but I want to commit what I have on my hard drive and disregard what is on the online repository.

I know I can do an initial checkout on a blank folder, then delete the downloaded files, paste the new files to the folder in Windows Explorer and 开发者_开发问答then do a commit. But I'd rather skip this step. There must be a way to do this. Right?

You can delete files directly in the repository in TortoiseSVN's "browse repository" dialog. There, you can also add files from your local drive directly using "Add..." or doing a simple drag and drop.
