If you need to merge some documents in DEVONthink, select all the documents you want to concatenate and choose Data > Merge from the main menu. Alternatively there’s also a contextual menu command for it.
Before you do so, here are a few things to consider:
- Merging text documents yields a finished RTF file, preserving the formatting in each document.
- Merging documents of with a mix of text and images yields an RTFD file.
- Merging a selection of PDFs yields a PDF file.
- Merging a selection of images also yields a PDF file.
Merging documents is dependent on the current sort method of the current group you’re working in. Regardless of the sort method, the files will be merged from the top selected file to the bottom selected file in the listing. If you need more control, you can set View > Sort > Unsorted and order the documents as you desire before merging them.
