Extension Renamer

Although its name defines its limits and usefulness, this freeware does what it does very well. Extension Renamer's comprehensible functions will suit any user even without a help file, although file-filtering instructions are available within the interface. In our tests the program quickly changed any file extension from within a selected folder to any new extension of our choice. With this freeware, you can easily control access to your personal files by renaming them to unknown file types. Since this application only changes file extensions and doesn't convert the actual file, its value is limited. Nonetheless, any user will still find the no-cost Extension Renamer worth keeping.
