Shell Extension Renamer

You can recognize a file type by the extension, unlike the computer does from a file’s internal code structure. For safety reasons, extensions are hidden by default, so they’re not changed by accident. Luckily, Shell Extension Renamer makes it possible to change the extension of any file directly from the context menu.

Needless to say that you need to go through a setup process so the application can clearly integrate into your system and become part of the context menu. However, in order for this to be possible, you need to make sure that .NET Framework is installed on the target PC.

Context menu integration is instantly done, and you don’t even have to go through a restart process to make it available. This means that right-clicking any kind of file reveals a new item, to change a file extension, right after setup is complete, and is also the only place from where to launch the core feature of the application.

Selecting the specific context menu item brings up a small panel with a short description of how to change the extension, and where to do this. On the bright side of things, the application comes with a list of various popular file formats which range from text to multimedia, and several specialized types.

Writing down a different extension than the ones already on the list automatically saves it for less effort later on. However, you’re free to add any combination of characters which defines the extension you need, because the application’s purpose is not to enquiry about the functionality. Sadly, you’re only able to change extensions for one file at a time, even if you select more files of the same type.

All things considered, we come to the conclusion that Shell Extension Renamer is a useful addition to your system commands. It helps out whenever you need to perform quick conversion which is possible through extension changing, or various other tests. Although it only works with one file at a time, it greatly speeds up the default method, saves new entries, and provides a rich list of presets.
