Using rar to compress and chunk up the file at the same time could be a good option, especially if this can be done on the client (for example using a java-applet as a file download/upload manager). Chunking on the client would be the only way to go over the 10MB limit as well.
GAE app development seems to be an exercise in being as efficient as you can, steering clear of restrictions, limits and time-outs. I like the idea of running rar server-side but I'd worry about hitting limits on individual page requests. For my needs I'm not so much bothered about the compression part - it's the chunking that would be great to have. I'm hopeful since this has been done for Java on GAE: http://code.google.com/p/google-file-service/wiki/GoogleFile Thanks, - Alex On Feb 22, 3:36 pm, Thadeus Burgess <thade...@thadeusb.com> wrote: > Well, with RAR files you can split them up into 1MB files.
