You can either program to upload your files to BigTable, Datastore of GAE (as Blobs, max size = 50mb), or you can make uploading them to your Google Documents Store (max size 100mb). 1st case can have slow performance.
If you want to store really LARGE files, you can check
http://aws.amazon.com/s3/ - Amazon S3 service, and then sync it with your GAE app somewhat.
