I am using Acrobat 11.0.3 with Office 2013. When I try to combine files into a PDF, in the Add Files browser, only pdf files show up. Office files like .docx and .xlsx do not display, even though those files are in the folder selected. When I try to sort by the filetypes, office filetypes are not listed amongst the supported filetypes. Currently, my workaround is to convert the files to pdf using the Office 2013 plug-in from within word or excel, but it would be nice if I could cut that step out and just convert the files directly from within adobe.
Please advise. Thank you.
