I would like to ask anyone out there who knows of a good free website that allows me to upload my gis data files to co-worker. Each project I am working on are quite large and would need to upload 1 GB each.
I think Dropbox would be a good solution for you. It will automatically sync files within a certain directory. I think the limit for the free account is 2g, which sounds like it would work for you.
If you use this I get a little extra space on my account :)
