There are a few things that you can do with a BDMV folder. You can use it to store Blu-ray movie files, or you can use it to convert Blu-ray movies to another format.
To convert a Blu-ray movie to another format, you will need to use a video converter program. There are many different programs that you can use, but we recommend Wondershare UniConverter. Once you have downloaded and installed the program, follow these steps:
1. Launch Wondershare UniConverter and click the "Add Files" button.
2. Select the BDMV folder that you want to convert.
3. Choose the output format that you want to convert the file to.
4. Click the "Convert" button to start the conversion process.
Once the conversion is finished, you will be able to find the converted file in the output folder that you specified.
