Replay Media Splitter 

Replay Media Splitter is a Windows utility that enables you to split movies and audio files on your computer. This application might come in handy if you need to extract certain segments from your homemade clips or audiobooks and export them as individual files.

The tool provides you with a built-in media player and waveform representation, supports drag-and-drop actions, and offers you easy-to-configure settings. Simply import your media file, indicate the start and end points, and click the Save button.

Unfortunately, the program offers a limited amount of useful features and doesn't work 100%. For starters, Replay Media Splitter supports only a few media formats (formats like SWF, OGG, FLAC, or AIFF aren't supported). The developer recommends you to try one of its other apps to convert the unsupported files to formats that are compatible with Replay Media Splitter. Also, the program's media player occasionally fails to display frames from the imported clips even though their format is supported.

Furthermore, you can easily find programs that are affordable, work with more media formats, and provide you with identical media splitting options plus other useful editing features (trimming, cropping, rotating, etc.).

In conclusion, I'd say you should try a different media editor for splitting your videos and audio files.
