突破Google Drive API导出文件10MB限制的解决方案

Hey everyone,

We're building a solution that generates PPTs packed with hundreds (even thousands) of embedded images, then downloads them directly in the browser using Google Slides and Google Drive APIs. But we've run into a critical roadblock: the Google Drive API enforces a 10MB per-file export limit, and our image-heavy presentations far exceed this cap.

Here's the sample method we're currently using to export and download our PPT files:

public byte[] downloadPPT() throws IOException { 
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream(); 
    driveService.files().export(getPresentation().getPresentationId(), "application/vnd.openxmlformats-officedocument.presentationml.presentation")
        .executeMediaAndDownloadTo(outputStream); 
    if (googleProperties.getRemovePresentationAfterDownload()) { 
        driveService.files().delete(getPresentation().getPresentationId()).execute(); 
    } 
    return outputStream.toByteArray(); 
}

We need to keep using Google APIs for this workflow—does anyone have practical, workable solutions to get around this export limit? Any insights or code snippets would be a huge help. Thanks in advance!
