Hello! I understand your concern about your downloaded files becoming .bin files and the risk of your SD card getting corrupted.
The .bin file extension is commonly used for binary files, which can contain various types of data. However, if you are expecting a different file format when downloading, then the .bin extension may not be what you are looking for.
To prevent your SD card from getting corrupted and potentially losing your files, here are a few tips you can consider:
1. Backup your files: It's always a good practice to regularly backup your important files to another storage device or cloud storage service. This way, even if your SD card gets corrupted, you will still have a copy of your files.
2. Scan for errors: Use your computer's built-in disk checking tools to scan your SD card for errors and fix any issues that may be present. This can help prevent further corruption of the card.
3. Avoid sudden removal: Make sure to safely eject your SD card from your device before removing it to prevent any data loss or corruption.
If you are encountering issues with downloading files that are turning into .bin files unexpectedly, you may want to check the source of the downloads and ensure that you are getting the correct file format. If the issue persists, you can try using different download methods or software to see if that resolves the problem.
