The only one of these three file sharing tools I am already using is Dropbox and this has been primarily for personal photo sharing and it works very well. After looking at the other two I find Dropbox to be the most straightforward. The idea of an independent platform for file sharing would be very useful if I were to embark on a new project which I’m sure I will at some point. When I was writing up my MSc thesis it would have been great as I kept everything on a memory stick and along with always forgetting to put it in my bag I also kept uploading photos that exceeded its size capacity. The good thing about Dropbox is that it can be used simply to store files; you don’t have to have them all on share mode. So with this, I could have kept everything on file and ready to use and I would have had the added security of it being downloaded on my desktop and backed up on the web. However, I have only recently noticed that there is a 2GB free storage limit which would quickly be eaten up with multiple images.
Google Docs seems to be almost exactly the same as Dropbox but I’m sure there are small differences. However, Wikis look to be a little more involved, almost like creating numerous mini blogs which could be very useful. I do plan to contribute to the Library Routes Project and that will give me some Wiki experience.
For the time being I will continue to use Dropbox but now [thanks to CPD23] when the time comes I am now familiar with other file sharing services.
