That doesn't seem unreasonable at all. There are plenty of power users like myself who do pretty much everything in Dropbox, and there are also plenty of tiny little files created every day that can count towards that. For example, deep down in my Dropbox I have a Code directory, which has plenty of other folders for most of the personal projects I work on. If I create a rails project, that puts in a bunch of basic files which can easily count for 100. I initialize a git repository on there and that can generate a few hundred more files. All of those add up quickly. Here's the results of a few commands showcasing the size of my personal dropbox, and I'm sure there are other power users who are similar to me. ls -aR Dropbox | wc -l 74397 du -sh Dropbox 32G (Just to note, .dropbox.cache accounts for 10G)
