By default, Windows hides file extensions to provide a cleaner look. However, viewing file extensions can be very useful, especially when you need to know the exact file type (like .jpg, .exe, .docx, etc.) for security or organizational purposes. In this guide, we’ll show you how to make file extensions visible in Windows.
What is a File Extension?
A file extension is the set of characters at the end of a file name that identifies the file type. For example, in the file “document.docx,” .docx is the extension, which tells Windows that the file is a Microsoft Word document. Common file extensions include:
- .exe for executable programs
- .txt for text files
- .pdf for PDF documents
- .jpg or .png for image files
Knowing the extension helps you quickly understand the nature of the file, which can be particularly important when trying to avoid malware or when managing multiple file types in a project.
Why Make File Extensions Visible?
- Security: Identifying potentially harmful files, like disguised
.exefiles that pretend to be.jpg. - File Management: Easily distinguish between files with similar names but different formats (e.g., “file.docx” vs. “file.pdf”).
- File Conversion: Knowing the extension can help when converting files from one format to another.
