Copernic: Free software that uses all of the top web-based search engines simultaneously. Has lots of good features, including storage of search parameters for later use.
File storage: Yahoo briefcase; FreeWebSpace.net's guide to online file storage space. I no longer recommend Visto or FreeDrive, because they are no longer free. When I first signed up with FreeDrive, I got a 50 MB account for free. Some time later, free accounts were downsized to 5 MB. And now, free accounts are being phased out altogether (and may be gone by the time you read this). In light of this, I asked if there was any plan to change their name, because FreeDrive no longer seems appropriate. I received a very polite response that indicated there is no such plan. FileGenie is no longer free either.
