Bob, it seems that the .zip files are not actually imported to your DT database, but only indexed, i.e., DT does not hold the actual file but only a reference to it – the .dtLink file you get when you export it.
Thanks for your response. What compression method do you advice I should use maybee stuffit? I need a complete compressed file that I can drag out off Devon Think pro so all the files are in it they way it was compressed.
Whatever compression format you want. Just make sure that the files are correctly imported. Check “Unknown files” on the Import tab to let DT import even those files it does not know of, e.g., compressed files.
Files that are only linked within DEVONthink show a zigzag arrow behind their name.
