Flagship Products

TreeSize

TreeSize is arguably JAM Software's most recognized product. It is a disk space management and storage analysis tool that allows users to visualize how storage is being consumed on their drives. TreeSize scans hard drives, network shares, and cloud storage, presenting a detailed breakdown of folder and file sizes in an intuitive tree-structured layout.

The product is available in several editions:

• TreeSize Free — a no-cost version offering basic disk space visualization suitable for home users.
• TreeSize Personal — an enhanced edition with additional features such as file searching, exporting, and charting.
• TreeSize Professional — a comprehensive version aimed at power users and administrators, offering advanced reporting, duplicate file detection, file search capabilities, scheduled scans, and support for network and cloud storage.

TreeSize is widely used by system administrators and IT professionals to identify space hogs, clean up storage, and manage capacity across large file systems.

SpaceObServer

SpaceObServer is an enterprise-oriented disk space monitoring solution. Unlike TreeSize, which is primarily an on-demand analysis tool, SpaceObServer continuously collects and stores disk usage data in an SQL database, enabling historical tracking and long-term trend analysis. This makes it particularly valuable for organizations that need to monitor storage growth over time, plan capacity, and generate detailed reports across large and complex environments. It supports scheduled scans, web-based access, and integration with database systems for scalable data storage.

ShellBrowser Components

For software developers, JAM Software offers the ShellBrowser line of components. These are development libraries that allow programmers to integrate Windows Explorer-like functionality into their own applications. Available for development environments such as Delphi, C++ Builder, and .NET, ShellBrowser components enable developers to display file system trees, list views, context menus, and other shell features without having to build them from scratch. This significantly reduces development time for applications that need file management capabilities.

SmartPOP2Exchange

SmartPOP2Exchange is an email management tool designed to collect messages from POP3 and IMAP mailboxes and forward them to a mail server such as Microsoft Exchange or other SMTP servers. It is often used by businesses that need to consolidate email from external mailboxes into their internal mail infrastructure. The software includes features such as spam filtering and virus scanning integration, helping organizations manage inbound email securely.

SmartSerialMail

SmartSerialMail is a bulk email and newsletter distribution tool. It enables users to send personalized mass emails to large recipient lists, making it useful for marketing communications, newsletters, and customer notifications. The software supports personalization fields, attachments, HTML content, and scheduling, giving businesses control over their outbound email campaigns.

HeavyLoad

HeavyLoad is a free stress-testing utility that puts a computer's CPU, GPU, memory, and disk under heavy load. It is used by IT professionals and enthusiasts to test system stability, evaluate cooling performance, and benchmark hardware reliability under demanding conditions.

ServerSentinel

ServerSentinel is a monitoring solution designed to keep watch over servers, network devices, and services. It continuously checks the availability and performance of systems and can alert administrators via email, SMS, or other means when problems occur. This helps organizations maintain uptime and respond quickly to infrastructure issues.

Additional Tools and Utilities

JAM Software offers a range of other specialized utilities, including:

• FileList — a command-line tool for generating file lists and exporting file system information.
• UltraSearch — a fast file search tool that queries the NTFS Master File Table directly for near-instant results across drives.
• Meta Info Reader — a utility for extracting metadata from files.
• Various audio and multimedia components for developers.

Services and Support

Beyond selling packaged software, JAM Software provides professional support and licensing options tailored to different customer needs. The company offers:

• Volume and site licensing for businesses deploying software across many machines.
• Software maintenance and updates to ensure customers receive ongoing improvements and compatibility with new Windows versions.
• Technical support to assist users with installation, configuration, and troubleshooting.
• Custom development and component licensing for businesses integrating JAM Software's technology into their own products.
