Question

What's the limitation on Acrobat?We tried Acrobat Standard XAcrobat PRO 2017Acrobat PRO 2020and latest Acrobat PRO DC 64 bit.Client: Server standard 2019 RDS .Recent issue is a scanned PDF file 315MB and consist of 598 pages.Does not open in any of the above mention Acrobat versions.Error "There was an error opening this document. The file is damaged and could not be repaired."The same file WILL open in Chrome or Edge Browser.The large pdf file was split in 4 smaller documents and could be open back in Acrobat.Another challenge is when users opens multiple (4 or 5) PDF files in the same profile to edit and search. (Each file could have 200 to 300 pages) The Acrobat software performance decrease even when the RDS server resources is not pass 50%. PDF file freezes or hangs.QuestionWhy is a large PDF file opening in Browsers but cannot open in Acrobat?Is there limitation in the software to manage this cant of workflow?

The problem is unlikely to be the page count or file size, but something else. (I have made and opened a PDF of one million pages before now).  The file probably is damaged, and when it's damaged different apps will try differently to repair it.
