Quickly inspect and adjust which apps open your files

After you install many programs, your system's file associations can get changed so that unexpected applications open certain file types. FileTypesMan provides a straightforward way to see every registered extension and file type on your computer, giving you a clear overview so you can regain control.

Features and capabilities

FileTypesMan shows a complete catalog of the file extensions and types currently registered on your machine. From its interface you can modify each entry's properties, repair broken associations, or remove unwanted context-menu (right-click) commands. Because it runs without installation, you can carry it on a USB stick and use it wherever needed. Although the interface is more suited to users comfortable with technical details, it’s a practical utility when an application has hijacked multiple file associations.

Restore and clean associations fast

Use FileTypesMan to quickly fix incorrect file-to-app mappings and tidy up non-functioning menu items. The tool makes it simple to restore sensible defaults or set preferred programs for specific extensions, saving time compared with hunting through system settings.

Recent update

  • A new View option called “Mark Odd/Even Rows” was added; when enabled, alternating rows are shaded differently to make it easier to follow a single line across the list.
