Hiding and Finding Extensions

What if you cannot see the file extensions? Sometimes your Windows system hides the extensions. You can bring the extension back by changing your Windows setting.

  1. Open any folder on your computer.
  2. Choose Tools then Folder Options.
  3. Click View.
  4. Uncheck Hide extensions for known types.
  5. Click OK.

PCs use three letter extensions such as .jpg and .htm. Macs can use 3 or 4 letter extensions such as .jpeg and .html.

As advised on the site MalekTips, watch out for multiple file extensions such as readme.txt.exe as these may be malware, to malicious software, waiting to infect your computer when opened.

If you see something like this type of file sent to you by email - don't open it! This file is not a text file, it is an application waiting to be let loose in your hard drive.

Did you know you can search by file type with Google?

If you prefer to see a particular set of results with a specific file type (for example, PDF links), simply type filetype:[extension] (for example, filetype:pdf) within the search box along with your search term(s).
