Sometimes, when you create a file with different extensions rather than widely used files in Windows (txt, rtf, etc), Windows automatically puts the traditional extension to the end of the file. For example, you want to create a file called helloWorld.php by using text file. When you create helloWorld.php, then automatically Windows creates it as helloWorld.php.txt. To prevent this you need to do the following:

1- In Windows Explorer, click Tools and Folder Options

2- In Folder Options, click View and uncheck “Hide extensions for known file types”.

3- Remove the txt extension from the file by renaming it.

Then, you should have no problem by creating file with unknown extensions.
