Hiya
I'm having this exact problem (on a very old, very fragile server - Moodle v2.3.3, windows 2008, MySQL) and we are moving over to a much more robust server, hence the backup and download scenario). I've been happily (!) backing up and downloading files for the last few days and now one just will not download. It's nearly 0.5GB admittedly, but I've managed to download others much larger (largest at 976MB), so I'm not sure if it's size or not.
I tried deleting the legacy course files, no joy. I removed them (in edit settings) before doing a back up, no joy.
Any ideas?
Many thanks
Karen
