The more people I work with, the more difficult I find keeping files together in one place, particularly if they are very large. Another issue is sharing files – it can get really difficult to keep track of file changes and amendments if you’re having to email the same document back and forth, especially when you get more than two people working on the same item. A great – and free – solution is http://www.dropbox.com. The basic storage option is pretty powerful, but storage size upgrades are reasonable for the Gigabyte players amongst you. Sharing folders is a simple matter of emailing an invite to colleagues. Recommended!
