Assume I have OCR-ed multiple PDFs in Abbyy FindeReader. Is it possible to reload the OCR results in Abbyy FineReader at a later time in order to correct OCR errors?
My idea is that I want to split executing the OCR and (at a later time) correcting the OCR results
Yes. You can use "File" - "Save" command to save the recognition results together will all the intermediate data.
