JAXenter has learned that TreeSize, the widely-used disk space management utility trusted by IT professionals and system administrators worldwide, will no longer provide technical support or updates to users holding perpetual licenses unless they transition to a subscription-based model. The move marks a significant policy reversal that has already sparked backlash among the software’s established user base.
What Happened
TreeSize, developed by JAM Software, has informed perpetual license holders that ongoing support—including critical security patches, bug fixes, and feature updates—will cease without a subscription commitment. Users who purchased lifetime licenses under the company’s previous model now face a choice: subscribe to TreeSize Pro on an annual basis or operate their existing software without vendor support. This transition effectively devalues the perpetual licenses customers purchased in good faith, transforming a one-time purchase into a recurring expense proposition.
Key Points
The subscription mandate reflects broader industry trends toward recurring revenue models, but the implementation has raised concerns about customer loyalty and corporate accountability. Perpetual license buyers argue they fulfilled their contractual obligations by making upfront payments, yet now must pay again to maintain support. Meanwhile, JAM Software positions the move as necessary for sustained product development and security updates. The company’s shift from perpetual to subscription-only support mirrors decisions made by other software publishers, though the timing and execution have drawn scrutiny from veteran users who feel abandoned.
For small businesses and independent contractors relying on TreeSize for storage optimization tasks, the forced transition represents an unexpected operating cost increase. Users managing multiple systems across different organizations now face multiplicative subscription expenses rather than spreading perpetual license costs across their infrastructure.
What This Means
This development signals the software industry’s continued march toward subscription-based business models, even when applied retroactively to existing customer bases. While recurring revenue benefits software publishers through predictable income streams and incentives for continuous development, customers lose pricing transparency and long-term cost predictability. The TreeSize situation may accelerate discussions among tech professionals about open-source alternatives and vendor independence, potentially reshaping the competitive landscape for disk management tools. Organizations should evaluate their software licensing strategies now, prioritizing solutions offering clear upgrade paths and respecting perpetual license commitments.
