I have just tried to get create a year end copy of my quicken file. Everytime I try I get the response - "Unable to open the data file". It appears that Quicken cannot open the copy it just made??? This has been a bug in Quicken Personal Plus 2011 & Quicken 2013. How can I make a year end copy and delete transactions in my current file up to a specific date if the wizard doesn't work?
