Keep your backup discs in a different location than your computer, such as a separate room, a fireproof box, or even a safe deposit box to protect them in the event of a fire or other disaster.
If you want to hide all open files on your computer, you can do it with one keystroke. On a PC, press the Windows key and hit "D" at the same time. Passersby will only see the icons on your computer desktop.
Before entering your credit card number on a Web site, look for a locked padlock icon in the bottom right hand corner of the browser window and make sure the web address starts with https: (the "s" stands for secure).
Never open attachments to emails or instant messages from strangers because they may contain viruses or worms.
If you mostly check email via a smart phone, to conserve your data usage change your email list memberships to "digest" mode so you don't get so many individual emails.
If your computer's desktop is cluttered with documents, folders, and downloads, go to your main File menu, select View > Arrange > By Name. Now your files will be easier to identify and organise.
To quickly refresh a web page to make sure you're seeing the latest version, add a question mark (?) to the end of the web address, and it will automatically refresh the page.
Choose a screensaver, such as a picture of your children or favorite holiday spot, that will motivate you to work hard when your energy is dipping during the day. Go to System Preferences > Desktop or Screensaver.
As you take digital photos, immediately delete the bad or unfocused shots right on your camera so you don't have to spend so much time uploading them to your computer and sorting them later.
To better organise folders on your computer, number them so they are always sorted in a consistent order. For example: 01_Homework, 02_Recipes, or 03_Finances.
