[QUOTE="krs, post: 1920957, member: 67742"] I don't have much time right now to do any experimenting, like run OCR with a lot more drive space available to see if that is the issue, but here are a few more details which perhaps ring a bell with someone. The original file was scanned directly as a pdf. It's a catalog of 164 pages, the scanned copy (no OCR) was 38.3MB When I run Acrobat OCR on that, I get to page 77 and then I get the Acrobat message, screenshot below. The critical part of the message is blank. Initially I thought OCR had a problem with the table on that page, but it turned out that was not the issue. When I continue to the next page after this Acrobat message, I get the same message again and that continues right to the end of the document. At the very end I then get the message in the second screenshot, ie out of memory. When I then check that document, I see OR performed up to page 77 and the rest are just images of the text. If I then run OCR on page 70 and onward, everything works fine for another 70+ pages, so that table on page 77 was not the issue. The end result of the complete 164 page document using Adobe Acrobat OCR was a 60MB document (done in three chunks) I then ran OCR using PDFpen - that software had no issue and completed the OCR task (all 164 pages) but the end result was a 120MB file (which I did not use). I still think the Acrobat OR software for some reason needs "real" RAM and can't use memory swapping with the SSD and based on that am wondering if there is a similar issue with an M1 or M2 Mac with only 8 GB of Ram. I have used Acrobat for many other functions an it's only OCR where I see this issue.
