Safety first - and back-up your files regularly - for example to a memory stick! If you haven't backed up recently, do it now!
There are a couple of free online solutions:
- Google Documents allows you to store documents in cyberspace - and you can choose whether or not to share the files (probably wise to make sure you have chosen 'don't share' in this case!).
- Another free option (for up to 2 Gb storage) is Dropbox, which has a synchronising function - making double-sure that your financial data are secure.
