Persistent Undo
When you run a task all changes are stored in a database so the record of changes are not lost when you close SongKong or restart your computer.
If it is later decided that you do not like any of the changes made by SongKong then simply use Undo Changes to change the files back to how they were before the fix.
This undo facility works even if the files have been moved or renamed and can be applied to sub-folders and individual files as well.
Preview Only
All tasks also have a Preview Only option so you can run the task and review the potential changes in the report before committing to actually making the changes
