Intuit has apparently made some very poor design decisions in their 'secret' file formats, resulting in the lack of ability to export/import investment transactions between files. This involves nearly 100 thousand transactions housed in about 15 different accounts from over the years, including various employer's 401k plans. Now I would like to have my complete investment history in a single complete file. HOWEVER, I made the mistake of leaving behind some of my retirement savings and investment accounts. So the logical thing was to leave behind accounts I no longer used. With my decades of experience in handling data, I know this has to be a structural problem. This is because I have experienced performance problems as the file grew, to the point it would take ten seconds or more for the update of a row of data in the register of all accounts. Granted over the years I made a few mistakes with Quicken in the area of retaining data in my current file.
