Why do I get an "unsupported file type" message when opening a Zucoin wallet backup file?

The Zucoin wallet app's exported backup file is designed to not open with normal filesystem apps by default, which is why you may see an "unsupported file type" message.

That message is expected after attempting to open the backup file directly.

This helps stop apps such as Google Docs, Google Drive, or Microsoft Word from automatically opening the file.

Opening the file in those apps could risk formatting, modifying, or editing the structured data in the backup file.

Some Android devices, such as Google Pixel devices, immediately suggest opening a recently downloaded file. For wallet backups, avoid opening the file directly and use the wallet restore process instead.

If you need to restore or back up a wallet, use the Help page.
