Combine PDFs in numeric filename order

Hi Antonio29154705tm48,

Thank you for reaching out.

If you wish to combine files in the order of the numeric names, you may move the files in the combine files window as required. Or you may select the files in numeric order to align similarly.

As you try to combine files, would you mind sharing the screenshot with us of where you messed them up? It will give us a clear idea of where the issue occurs, and we can suggest the correct workflow.

For more information on Combine files, refer to the following help page: https://helpx.adobe.com/acrobat/using/merging-files-single-pdf.html. 

Thanks,
