TreeSize Sparks Outrage Over Perpetual License and Subscription Policies
TreeSize Perpetual-License Support Policy
Users of the popular disk space analyzer TreeSize are encountering unexpected friction as software vendor JAM Software changes its maintenance policies for perpetual licenses. According to reports, customers who own perpetual licenses are no longer eligible for ongoing software updates, bug fixes, or technical support once their initial maintenance period expires, unless they convert to a recurring subscription model.
The Tech TL;DR:
- The Core Change: JAM Software has shifted most TreeSize editions to subscription models since 2025, leaving perpetual-license support contingent on active maintenance renewals or full subscription adoption.
- The Access Bottleneck: Under long-standing company policies highlighted by frustrated users, perpetual license holders lose access to license keys and installers for older versions once their support period lapses.
- The Personal Exception: Product manager Hendrik Christ confirmed to Ars Technica that the company currently maintains “no plans to discontinue the sale of perpetual licenses for TreeSize Personal,” which includes 12 months of updates and support.
Understanding the Maintenance Cutoff and Installation Restrictions
For users, software lifecycle management dictates predictable patching schedules and reliable access to binaries. However, as perpetual-license maintenance periods expire for early adopters of TreeSize, users are discovering that extending support requires pivoting to software they already possess the perpetual right to run.
Compounding the frustration for users is JAM Software’s policy regarding download availability. According to user reports and support documentation, the company does not provide license keys or fresh installers to perpetual license holders after their maintenance window closes.
Writing for Ars Technica, product manager Hendrik Christ clarified the current scope of these changes, noting that perpetual licenses remain available exclusively for the Personal edition of the software. This tier bundles 12 months of updates, support, and access to legacy downloads, with options to extend that specific support window.
