I have/use multiple technical documents for work. A big part of this is searching different PDF libraries via the index.pdx files within the PDF libraries. From time to time I have need to add or fix these .pdx files. Currently on Win7 is use an old opy of PDFpro to do this function. But I want to rid myself of windows completely but I can't find a app that would allow me to created index.pdx files for searching. Any advise?
