Do you use Dropbox to back-up your files? (Because you are backing them up somewhere other than on your local machine, right?)
TCU folks can use their M: drive for free storage. However, some users may have had a set-up with Dropbox prior to their arrival at TCU, or may prefer the user interface of Dropbox or the ability to store larger files (Dropbox has tiered pricing, but offers some storage for free).
If you are using Dropbox, this is a pretty convenient Dropbox tips and tricks reference sheet.
Also, the same site also has tip sheets for Google Docs, Skype, Gmail, Twitter, Google Reader, the Windows CMD prompt, etc. If you find yourself frequently searching for shortcuts in your favorite programs, it might be worth a look to see if there’s sheet that meets your needs.
