I was speaking to a developer friend of mine who told me he pulled some images out of a JAR file. What’s that and how do I pull stuff out of it?
The letters J.A.R. stand for Java ARchive and it’s really similar is structure to a standard ZIP file. In fact, most archiving software will open up this archive and show you the files that live inside it. If you really want to look inside it, I would recommend using 7-Zip which is a free archiving package.
Obviously JAR files are more useful it you actually want to execute them. In order to do this you need a JRE, a Java Runtime Environment which you can download for free too. Once your JRE is installed, all you need to do is double-click on your JAR file and the application will execute, whether it’s a dvd discount voucher application, a game or any other JAR file you may have downloaded.
I have collected numerous unneeded and unwanted toolbars across the top of my internet screen. I would like to be able to delete some of them but although they seem very good at telling me how useful they are, they are hopeless at telling me how to get rid of them.
I’ve found that if I press the F11 key this clears them temporarily but I then lose the ability to see the status bar at the bottom of the screen. Can you help?

I have recently transferred all my photos to CD-Rs, with one disc for each topic. How long can I store them like this before transferring them to new discs? Having seen floppies become unusable over time, how do I ensure that there will always be a medium and method of saving these photos for posterity?
