Replacing multiple ZIPs with fresh copy (S3)

[CABrouwers]

I back up on Amazon S3 and have set up SFFS to break up files larger than 5GB into multiple zip files. Now that S3 multipart upload has been implemented, I would like to get ride of all those zip files and upload a fresh copy of the file above 5GB. Any suggestion how to that as painlessly as possible ? hanks.

If there aren't too many, the easiest way would be to delete them with Amazon's online browser interface and then the synchronizer will upload them again with the new settings.
