It is really a good idea!!! I have been following it for years now. I have used a specific directory for entire of my modified data, the docs, photos, modified themes, application data settings (browser settings, templates, playlists), even my browser opera is in a fixed directory and I have added all the shortcuts required accessed by using hoekey or in quick launch and the registry modifications of the above mentioned registry settings help to keep all the shortcuts handy and I really don't have to add any of my existing shortcuts too. I further have made out a fixed directory of the temp environment, it is essentially in a separate partition and it houses the temporary internet folder and cache of opera too. This helps to check the overall thrashing of the disk and the directories can be cleaned easily without digging deep. This process can be utilised without having to install your itsy bitsy utilities like power calculator, opera, clear tweak and innumerable others!! The best part of this whole method is you can back up your data fairy easily by backing your folders which are located at one fine point only.
