Dropbox is great and I use it almost exclusively for sharing photos.
80%-90% of this sharing is for work projects, where we (I) will create a folder of photos for a project that that is temporary, that is, for some days, weeks, or months they will be needed, then discarded from the Dropbox. I save them to a "deep storage" hard drive or DVD-R, but I do not want them taking up Dropbox space.
I have computers at home and at work, and a laptop that dual-boots to Windows 7 and Ubuntu 12.04. There are half a dozen other co-workers with various setups.
What I need is a "master" Dropbox that rules and determines what is in and what is out.
For example, if I do not use my laptop for a week, and purge the Dropbox from my desktop, the next time that I turn on the laptop it will re-populate the Dropbox with the previously purged files. And, even if I fix it in Windows, the next time I boot the laptop into Linux, it does it again, since there is a Dropbox account there, too.
One solution that comes to mind is to delete everything from the laptop and assign the Dropbox to a different email account, but this is cumbersome and I would prefer to keep it simpler.
Any advice or ideas? Thanks!
