I bought a guide in PDA, but would really like to have it in PDF so that I am able to highlight and put notes for myself. Is there an app or any way for me to convert this file?
Converting PDA to PDF is not possible because there are no applications designed for this type of conversion and there should be a different approach. Since PDA is a graphical format, you can use the default application to view it and print it virtually to PDF format. You can do this with CutePDF Writer. This application installs as a virtual printer which enables you to "print" your files to PDF format. Simply open your file after you install CutePDF and select Print function from the program. In the Print window select CutePDF and then click Print and that's it. Your file will be printed to PDF format.
