感谢您告诉我们，很高兴您能解决问题。
Thanks for letting us know, glad you could resolve the problem.

要了解原始问题：
你的意思是图册文件太大（图像分辨率）？ 或者太多的图册页面（如5张图册页面）？ 你的话被错误地翻译成英语“太多”，不幸的是没有意义。
To understand the original problem:
Do you mean that the atlas file was too large in size (image resolution)? Or too many atlas pages (like 5 atlas pages)? Your words were incorrectly translated to English as "too much" which does not make sense unfortunately.
