amazon s3 limit amount of upload for each user

I'm new to Amazon S3 and I want to write a little "dropbox" application with php. Therefore I want to limit the amout of data a user could upload to a specific limit, let's say 1GB. I want to create a folder for each user (does S3 support folders or only filenames like /dir/filename.extension?). Is it possible to get the size of the folder of a user and display e.g. a progress bar with the space curently used? Do I have to perform a check whether the space is completely used each time a user wants to upload a file or is there a solution to set the limit for directories directly in S3?

Thanks for your help!

S3 only has the concept of buckets, and buckets cannot be nested. Furthermore, bucket names must be unique across all of S3 -- all users' buckets.

The default account limit is about 90 buckets for a single AWS account, so factor that into your design.

You can get sizes of buckets and individual files in a bucket from the SDK, though it will be a lot cheaper if you have any way of keeping that information locally and not having to round-trip to AWS to get it.

There is no built-in quota support that I know of, so you will have to track this yourself. Plus, with a 90 bucket limit, you might need to implement some kind of virtualized directory scheme inside of an S3 bucket to allow multiple users' data in the same bucket.
