This is my first post here. I have enjoyed reading some posts already, it looks like a great forum.
My Question: Which PDF Aps can open encrypted files and use the indexes? I have catalogs on PDF of which most work but one in particular will not open in iBooks or other Aps. Sometimes it says it is encrypted and sometimes it says it is the wrong format. I have been trying to find out whether iAnnotate or PDF Expert will do it.
Also, these catalogs I have, have indexes when I open them on my pc but not on the iPad. Is ther an Ap which will use the indexes?
