Lesson 4: Local File Management (How-To)

Find out which programs or applications open these types of files.

One way to find out how file extensions are associated with programs is to look them up.

• Open a new Browser window (under the file menu)
A new window should open
- You should see the CHS home page

• In the bar that says "address" or "location" or "URL" type http://www.google.com
This will take you to a search engine
- There should be a Google header and a text field to enter your search

• In the text field type "file extensions" and click Google Search
A new window should show up with links to a ton of different web sites.
- This page can change everyday so it will be hard to confirm what it looks like

Tip: You may experience the frustration of using a huge search engine to look up the definition of some computer terms. Later in these lessons we will provide some information on more efficient ways to do this. You can also try a web site that worked in early August of 2002 is http://filext.com/.

• Look up the various file extensions to find the answers
an example might be .txt = Text File (open in Notepad, WordPad, Word, Simple Text)

Type a short document listing the file extension and the program or application that opens it.

• Open a word processor

• Type a list for what you have found out like the example above

Save this file to the desktop.

• Choose File -> Save As.. ->
A window will pop up asking where you want to save and what you want to call it

• Choose to save this on the desktop, and call it file_extensions

Hint: You should add the file extension that is appropriate for the word processor you are using, or choose .rtf so your document can open in multiple word processors.

E-mail it to yourself as an attachment using webmail (your 4j account).

• Open your webmail account (the next 4 steps tell how to do that.)

•To start, click the blue text in the first line http://webmail.4j.lane.edu.
This sends you to the Webmail Page.
-On this page it should say 4J Webmail Pilot on the menu bar.

•Next, click the first link (blue text) Squirrel Mail.
This takes you to the Webmail login page.
- This page has a place to put your name and password and a login button.

Tip: The places to put your name and password are called text fields

•Here you should enter your username (the same one that you used to log in to the computer), and your password (also the same as the one used to log in to the computer).

•Click the login button.
This will bring you to your e-mail folder INBOX.

• Click Compose to open a new message

• Enter your e-mail address, a subject (file extensions), and some text to the body of the message.

• Below the body of the message you will see two buttons next to an attach field.

• Click Browse...
A window will pop up asking you to locate the document you want to attach

• Navigate to the the document you saved on the desktop and click ok
The name of the file will be in the attach field of your message to be sent.

Very Important

• Click add next to the browse button.
This is the only way the attachment will go with the e-mail
- You will see your attached document below the attach field.

• Click send.

• Check your mail

• After you see that you received your e-mail you should delete the document from the desktop.
