It can be quite important to know some things about your computer and the items you have stored on it.
To find out about your system, choose the first item in the Apple Menu "About This Mac".
A window similar to this will open and you will see the basics about my system.
I am running OS 10.3.9
I have 768 MB (megabytes) of RAM (Random Access Memory) installed.
The processor is a G4 running at 800 MHz (megahertz)
If you press the "More Info" button you can get lots more information about your system.
Selecting the "More Info" button will open the Apple System Profiler, which can tell you all kinds of things about your Mac, much only a tech will understand but can be quite valuable if you are experiencing problems and you are talking to a tech, but there is some info that can be of use to you.
You can get more detailed info about your system, see which devices are attached to your Mac, the frameworks and extensions the operating system is using (tech stuff), what applications (and their version) are in your Applications folder, and view the logs which are saved when your system or an application crashes (pretty handy for getting help figuring out what is happening when bad things happen).
Above you can see I have a hub attached to one of my USB ports, which in turn has a Microsoft 5-Button Mouse and a Logitech USB Keyboard attached to it. You can also see my Firewire Hard Drive and all it's volumes. Attached to the bus is my internal hard drive, named Bilbo, and the built-in CD/DVD drive. This is only the beginning of what the Apple System Profiler can show you. Feel free to poke around in the Profiler, there is nothing danerous about it.
To get information about a file, folder or any other item, highlight the item in the Finder and choose 'Get Info' from the File Menu (or use the keyboard shortcut apple(command)+I). A window will open like the one below. The information in the windows will vary depending on the type of item you choose.
This one is of my hard drive and the two below are of a file. Each has a series of panels which you can open (or close) by clicking on the triangle.
General: The pertinent information for the item
Name & Extension: Here you can rename the item and can choose whetheror not to show the extension
Content index: If a folder or volume is indexed the find feature will be able to search the text of the files. Here you will see if and when the folder was last indexed.
Preview: Here all you see the icon of the file or folder, unless the file is plain text, sound, graphic or movie. If so, you will see a thumbnail of what is in the file.
Ownership & Permissions: Here you can control access to the item by others.
Comments: You can make notes about the item which are viewable in the List view also
If the item is a file or folder you will have the opportunity to "Lock" the item to prevent it from accidentally being trashed.
If the item is a file, you can make it a "Stationery" item. This saves the file so that when it is opened again, a copy is created and the original file is preserved.
Also if the item is a file, there is the option to choose which application to open the file with.
Open with: If the item is a file you will have the opportuinty to change what application it will open in when double-clicked. You can also change all the files with this extension to open in your choice by using the "Change All" button.
This can be very handy if you don't have the application the file was created with.
Suppose you receive a file from a friend that is a .doc and you don't have Word, you can choose to have it open in AppleWorks and if you choose "Change All", then all other .doc files will now open in Appleworks simply by double-clicking on them
