I need to have someone help me find a very simple, defined explanation of the difference between Adobe Acrobat and Adobe Reader, the advantage of Acrobat and the necessity of Reader. I need to upgrade Acrobat and I need to justify it. I currently use it to take several files and put them together to create one large file, that can be updated as we go.
It's very simple.
Reader is used to view and print PDF files only (with the exception of some specially enabled files). Acrobat is used to create PDF files (Reader cannot do this) and modify PDF files (like you are doing now).
To continue merging seperate files in to one file, you have to have Acrobat.
