Description

While working on this file saver we are facing issue. When we save file using path and on that path if file not present still its downloading with provided name with not content as corrupted file. Ideally it should popup message as file not found.

Research direction
Review the FileSaver.js source code to understand how file content is obtained from a path. Focus on the saveAs function to see if there is any validation for file existence. The issue reports that a missing file still triggers a download of a corrupted blob, so add a check for file existence before creating the blob. Consider linking an alert or error when the file is not found. See comments for any additional context.
