Show all file extensions

Question

How can I avoid being duped by hidden file extensions?

Answer

This question was answered on March 16, 2006. Much of the information contained herein may have changed since posting.

A file extension represents the last three digits of any file For instance, the file extension of ‘program.exe’ would be ‘.exe’, and that instantly identifies the file as an executable A file ending in ‘.jpg’ means that the file contains a picture; at least it should The problem is that a malicious person can alter a file name to look like a picture file even though the actual file extension makes it an executable Here’s how to prevent being duped:

1. Open My Computer.

2. Go to Tools and click Folder Options…

3. Click the View tab.

4. Under ‘Advanced settings’ you’ll see a checkbox labeled Hide extensions for known file types; uncheck the corresponding box.

5. Click OK to save the new settings.

Now all files should desplay their actual file extension, regardless of how common it may be Cheers!
