Before deleting a list or library in SharePoint, please consider the following:
- Have all the files been backed up?
- Are there any workflows, items, or properties to be deleted which might save the list or library?
- What would be the best solution to the problem in this case, deleting the list or library or another option?
- Will I still have access to the data I need after deleting the list or library?
- Are there any documents being indexed in the list or libraries that will no longer be indexed after their deletion?
