Change File Extension One-by-One and in Bulk
The installed applications on your computer can only open specific files, such as PNG images or PPT files, but not others like JPGs or PPTX. To open these files, you need to change their file extension to the corresponding one, which can be done in Windows 10.
What is File Extension
The file extension, also known as a filename extension, is a suffix at the end of a computer file. It's part of the complete file name, which includes both the file name and extension, separated by a dot. The operating system uses file extensions to determine which application to open when a file is double-clicked.
There are, like hundreds of existed file extensions. Below we have listed some common file extensions.
PNG stands for Portable Network Graphics, a lossless image file format.
HTML, short for HyperText Markup Language, is the standard markup language used to create web pages. It is the backbone of any website, allowing users to structure and format content, images, and other media on the web. HTML is used to define the different elements of a web page, such as headings, paragraphs, links, images, and more, making it the fundamental language of the web.
PDF stands for Portable Document Format, a file type originated by Adobe that maintains formatting in distributed documents.
EXE: An executable format used for programs you can run.
The original Microsoft Word document file extension was DOC, but it was later changed to DOCX in 2007, when Word documents transitioned to using the XML format.
XLSX is a file format used by Microsoft Excel, a spreadsheet program. It was introduced in 2007 as a replacement for the older XLS format, and it has since become the standard for saving Excel files. XLSX files are actually a type of ZIP archive, containing multiple XML files that describe the spreadsheet's structure and data.

How to Change File Extension in Bulk
The first method allows users to change file extensions one by one, but what if you want to change several file extensions at once? We're curious about this question and wonder if there's a method that can accomplish this task all at once.
Unfortunately, NO.
We've tried using the method of selecting all files and right-clicking to bulk change the file extension, but unfortunately, it doesn't work. Even though you can select all the files, Windows will prompt you for confirmation each time you change a file extension, making it a tedious and time-consuming process.
You're saying that the methods pages are suggesting to change file extensions in bulk are actually not valid.
