Most things accumulate and need pruning. Some people would like to do manual pruning but I favour a time-based approach of keeping everything in monthly folders. Monthly folders so basically with every new month, some things are not carried-over but are still there and can be referenced if necessary. So basically, a new month helps with reducing the accumulation of old stuff which bogs down a system.
