We'd recommend you not ever stop/start through the aws console -- this is 
basically guaranteed to cause problems with your instance.  Always use the 
cloudman interface (on your ec2 instance -- http://<ec2_instance>/cloud) to 
terminate, and then use usegalaxy.org/cloudlaunch to restart it.

Everything will be in /mnt/galaxyData/files (which is symlinked to 
/mnt/galaxyTools/galaxy-central/database/files).  Note that the filenames will 
be by id (like files/000/dataset_001.dat is dataset id 1, etc), and not 
particularly accessible in this format without a little extra legwork.
