File compression and backups.

Compresing data is like compressing any other physical item. The aim is to make it smaller. The only difference is on a computer it is done digitally. When you compress something on a computer it makes the file or document about 95% small. If something was 1gb it would end up being 50mb. See This makes compression very handy for making backups. In this post i am going to show you how to compress a document, then save it to a CD for a backup.
Step 1.....In fact this is the only step
Go to the file you wish to compress, right click>Send to>Compressed/Zip folder.
And your done.
The compression ratio of most file is something like 80-95%. So you will save allot of space compressing files.
See below for a pic to make it easier.

One you have compressed the file you should see a folder appear with a zip on it. Right click on it again>Sent to CD/DVD drive. If a blank disk is in the drive it should burn straight on. If a disk is not present it will say it is awaiting a disk. Once one is inserted it should begin.
