The company behind the disk space analyzer TreeSize has irked some users by no longer offering support or updates for perpetual licenses beyond their maintenance period unless customers subscribe. Further frustration has come from JAM Software's long-standing policy of not providing license keys or installers to TreeSize perpetual license holders after that support period ends.
Since 2025, JAM Software has been transitioning most TreeSize editions to subscription models. Today, it sells perpetual licenses only for personal use, which include 12 months of updates, support, and “downloads of older versions, and your license,” plus the option to extend the support period. TreeSize currently has "no plans to discontinue the sale of perpetual licenses for TreeSize Personal," product manager Hendrik Christ told Ars Technica.
As perpetual-license maintenance periods expire, customers are discovering that extending support now generally requires subscribing to software they already own the right to use.
