The document could not be saved. This file is too big for the current operation.
I am trying to combine two parts of a book into one, the files are 1.69 GB and 1.82 GB. The files have 1147 pages combined. I am using Acrobat Pro XI on a Mac running 10.11.6 which has a 2.5 Ghz i5 Processor and 4 GB RAM with 23 GB of free space on the SSD HD.
I get the message "The document could not be saved. This file is too big for the current operation."
I have tried saving it to the local hard disc, a flash drive, and network attached storage after a binder has been created but get "the message." I have searched these forums but have found only similar questions so here it is again.
