Since I've been doing a lot of life reorganization after IndyGeek, I've been trying to purge a lot of junk from my life. I've been a long time user of Sparrow (since the beta days), and I've amassed a LOT of email addresses in the auto-complete cache. I've been wanting to purge this information, since I've only emailed some people a total of 1-2 times and others contacts I just don't need to email any longer.
Looking for a solution, I turned to the forums and knowledge base on Sparrow's website. Unbelievably, there was no solution to be found. I guess people don't like to clean up their caches like I do. I looked inside the Library folder in my Finder, as so many of the application support items are found there, but I couldn't seem to locate it. I was frustrated - so much in fact, I briefly switched back to Apple Mail.
I say briefly because with the help of my wife, I was able to locate the suspect files and render them incapable of destroying my auto-complete sanity. For those of you who are wanting to know the secret, here's how.
Cmd + Q to close Sparrow completely. Go into the ~/Library/Application Support/Sparrow and delete the following files:
- .../useraccount.sparrowdb/recipients.db ('useraccount' is the email account name in Sparrow. In my case it read .../email@example.com/sparrowdb/messages.db. You'll want to look for the same.)
Relaunch the application (reboot/logout/shutdown of the OS X user profile isn't required) and begin to type the first letter of a sender's name. You should now only see the results of what is in your Mac's Address Book, rather than all the other junk that was there before.
I wrote to Sparrow's developers and asked them to put this information in the knowledge base. As of this posting, it still has not been added. I hope the devs consider my request.
UPDATE: It seems that the default setting in OS X Lion is to hide the user Library folder in Finder. To make this folder visible, simply launch Terminal (either via the Applications folder or Spotlight) and type
chflags nohidden ~/Library/. Doing so will make the Library folder in your Users directory visable.
