As a busy musician, you may begin to accumulate a lot of sets in your active set list. You can go through the process of manually archiving each set by going into the Editing Mode and choosing Archive Set from the Action Menu. But another option is to turn on and configure auto-archiving of sets.
When you have a number of older sets in your list of active sets, OnSong will prompt you to auto-archive your sets. This makes the sets accessible in the future through the Archived list of sets, but cleans up the Active list of sets for faster access at the venue.
If you do choose to auto-archive sets, the timeframe of one month is automatically selected and older sets are moved to the Archived list. You can turn off auto-archiving of sets or configure the timeframe to keep sets active under the Utilities Menu » Settings » Menu Settings » Songs.
