What happens if you want to keep something around for your records, but you don’t need to access it often? This is a perfect situation for archiving tasks and projects. This can be handy when you need to go back and evaluate prior accomplishments. When you check off and complete a task in OmniFocus, this task doesn’t get deleted - rather, completed items remain in the database until you remove them. If you are an iOS only user, you can click here to see the options that OmniFocus for iOS provides to help reduce database size. There are a couple of methods available using OmniFocus for Mac if you’d like to quickly reduce the size of your database. Scroll all the way to the bottom of this popover to locate the Database Statistics section.
In this window, click the blue underlined text labeled Learn more about what kind of information is sent to bring up a popover containing a variety of statistics. Navigate to Menu Bar > OmniFocus > Preferences, then switch to the last tab ( Update for Omni Store customers, or System Info for Mac App Store Customers).
