For example, Windows has a folder called My Documents where it will put your Word, Excel and a bunch of other files. If you make a habit of storing any file you create in My Documents , you'll only have to back up that one folder instead of looking all over the place for files you've created. An important thing to remember is that backups should be made on reliable removable media. Backups on your hard drive don't do any good if the entire drive fails. Also, if they're really important, backups should be kept at a different location than the computer.
Backups are no good if they're sitting next to the computer in a fire.
One of these is partitioning, and the other is changing your file system. Partitioning involves splitting one large physical drive into smaller logical drives. If you have a drive larger than two gigabytes, you should consider partitioning it into smaller drives. For example, if you had a six gigabyte drive, you could partition it into C, D, and E drives. You could also put backups of files here, although they could be lost if the entire disk crashes.
