Split files same size as original

[Scott Previty]

When we split a file, typically a collection of 100+ pages of construction blueprints, into individual files per page, each split document is the same size or a little larger than the original document.  If the original doc is 80 MB, we could end up with 135 documents of 80 MB each (10.8 GB total).  This is putting tremendous strain on our file server storage.  

If we follow-up by batch processing the split files to PDF/A-2u, the processed files are a much more reasonable (and expected) size but not always processed correctly.  Any idea of why Nitro Pro 13.67.0.45 may be splitting the files to such unrealistic sizes?
