Question: Hi, I'd like to ask if there was any way I could get a full version trial of VeryPDF Advanced PDF Tools Command Line. I want to test applying the metadata from an XML into a PDF file before purchasing the software. The trial version doesn't let me test that. Is there anyway this is possible? The sooner I can get a full version, the faster I can test and possibly purchase your software. Thank you for your time.
Answer: This is the trial version limitation, by the trail version of VeryPDF Advanced PDF Tools the function of setting metadata from an XML into a PDF can not fulfilled as even if setting metadata from an XML into PDF, trail version limitation will clean all the added metadata. In order to show the practicability of this function, I will show a demo here. So you can rest assured to pay for it, by the full function version, this function could be accessed without any problem. And in the future, we will remove this limitation of trial version then you can fully test this software freely. Please check more information of this software on homepage, in the following part, I will show you how to use this software.
Step 1. Free download Advanced PDF Tools Command Line
