I have just bought an iPad Pro and am finding that pdf files I have stored in Box open in Box’s native reader rather than adobe reader. I want to be able to edit them (highlight, mark-up etc). Ideally I want to use ProDC but I don’t think that is an iPad app(?). Just opening in reader would be an improvement. ANY SUGGESTIONS?
You can't run Mac or Windows apps on iPad. The world of iPad is very different, and very limited. Similarly, you can't change the default app that opens a type of file. However, what some apps allow you to do (for example, Safari) is open a PDF _then_ send it to another app, and that's how you get a copy of the file into Reader. It's clunky, but then again the iPad is really just a big phone.
Sorry for the delay in response.
As you need to open the Box file in Acrobat Reader, you need to first save the file to local.
Take help of the steps mentioned in this forum thread iPad Dropbox download for offline viewing with the similar query.
You can also refer the steps mentioned in this help link Opening PDF Files in Reader for iOS (iPhone and iPad)
Once the files saved in Local, you can open and edit the file in the Acrobat Reader mobile application.
Hope the information helps.
