I have been using quicken for 25 years, and have kept the same data file for all of that time. Every time Quicken has asked me to upgrade the file over the years, I've done so, and so I am pretty sure I'm running a current version file, and the file validates fine. Quicken has started to noticeably drag doing basic transactions, where simply adding a transaction to some of these accounts' registers takes 15-30 seconds on a modern computer with plenty of memory and CPU available and an SSD. I suspect it's due to the sheer volume of transactions it's processing - the QDF itself is 160MB, has a bunch of long-closed accounts and transaction history that really isn't relevant, and I'd like to drop all but the last 5 years or so of transactions from the current file.
I had tried creating a year-end archive with file → copy or backup using the appropriate date ranges and selecting remove files, but this doesn't really do what I need it to, I think because it says "only reconciled, non-investment, non-transfer transactions will be removed" but honestly even the stuff that meets those criteria didn't get removed last time I tried it. I thought about maybe exporting the dates I want from the current file from "all accounts" and then import to a newly created file, but I'm also trying to avoid having to set up my online services all over again in the new file, and also maybe not carry over all of the accounts that are inactive. What is the recommended way to handle this?
Current version is classic deluxe, R67.10 on windows 11, but the last time I tried the archive was a while ago.
