Writes a file with the given data.
You provide either a container value or some text. For text you can optionally define a filter like base64 or Hex.

See also Text.WriteTextFile for writing text files with specific encoding.

See FileDialog functions if you like to show a save dialog to pick a destination for the file path.
If you need to create directory first, please use Files.CreateDirectory function.

This function requires a native path. Use Path.FileMakerPathToNativePath to convert a FileMaker path to a native path if required. If you like to have the user choose the path, you can use FileDialog functions.
For Server be aware that server has limited permissions and may not be able to access all files on a computer.
