There are many bugs which just gets unnoticed, because of their sheer inherent triviality. Windows in order to make lives of its user simpler (and lamer), sometimes have faulty default settings which could lead to major problems. One such issue is the “extensions settings”.
Windows in some cases doesn’t feel the need to name the files with proper extensions depending on the file type. This can drive the general users as well as developers go nuts.
In a classic example, if you type an HTML code in notepad and save it, the default filename would be like “HTML_file.html.txt” instead of “HTML_file.html”. How to change this default setting?
1. Open Windows Explorer
2. Click Tools menu > Folder Options > View
3. Uncheck or clear out “Hide extensions for known file types”
Performing these 3 simple steps, makes Windows always show the file extensions.
