PDF合并PDF包的时候，软件容易自动关闭

Hi @31402019 

Thanks for sharing the video.

To investigate further, there are more details required.

• The files you are combining seem to be a lot in numbers. Hence the file size would also be increased. Could you confirm the file size?
• The PDF preview is also not visible here, so try this and see if it works: Acrobat>Preferences(ctrl+k)>Security (Enhanced)>disable "Protected Mode at Start-up", "Protected View" and "Enhanced Security">OK>close and reopen Acrobat. [Windows only]

It could be any one of the files is problematic, so try a bunch of files first and then add another. Did it help?

As suggested, ensure you have the most recent update installed for Acrobat.
