File Extension Changer .NET (often referred to as ABK File Extension Changer .NET) is a lightweight, free Windows utility designed to easily change the file extensions of single or multiple files.
The tool was created by ABK Freewares to provide a safer and more convenient alternative to manually changing file extensions through Windows. It eliminates the need to continuously toggle the “Hide file extensions for known file types” setting within the Windows Folder Options. Key Features and Capabilities
Bulk Renaming: Allows you to change extensions for multiple files simultaneously.
Context Menu Integration: Integrates seamlessly into the Windows right-click context menu (via registry keys) for quick access.
Drag-and-Drop Support: You can drag and drop files or entire folders into the program interface for quick processing.
Advanced Processing: Capable of working with read-only, hidden, or system files.
Portability: Features a completely portable version, making it easy to carry on a USB drive without leaving leftover items in the Windows Registry.
Backup Option: Allows you to create backup copies of your original files before converting them. Technical Details
System Requirements: Requires the Microsoft .NET Framework 3.5 to run properly.
Compatibility: Officially developed for older Windows versions (XP, Vista, and Windows 7). While it may function on newer Windows versions (like Windows 10 or 11), users looking for modern native alternatives frequently use similar tools like File Extension Changer by Daanav.
Note: Renaming a file’s extension only changes the file type association. It does not convert the actual data inside the file (e.g., renaming a .txt file to .docx will not magically format it as a Word document and can make the file unopenable).
