I discovered this procedure while working with a client recently. I wonder why Intuit has hidden this feature, but I’m glad I know how to do it now. I’m pleased about this since it’s common to have to do maintenance on large database files from time to time. I was not even aware that Quicken included this feature. I’ve supported many people who use Quicken, and this is the first time that I’ve had to reindex a Quicken data file. The article does also suggest exporting the data in QIF format and then re-importing the data into a new file if the reindexing fails or does not solve your problem. You can read a more detailed explanation of these reindexing instructions on Intuit’s web site. Give your file a new name and save it to your desired folder. Once it has finished, then go to the File menu and select Save A Copy. Open the Accounts window and then simultaneously press the Command, Option and B keys on the keyboard.Here are instructions on how to reindex your Quicken Data File.
