What Our Customers Think Of Us

Thank you, JAM Software, for dreaming up this application. It helps me manage local and NAS Storage more efficiently.

Kevin Tran - CT Corporation, A Wolters Kluwer Company

SpaceObServer is a properly designed application with extensive uses and features which might come in handy to a large group of computer users.

Read the complete review.

Working with large-scale archives used to ask of the end-user unreasonable amounts of patience as discrepancies would be discovered during cross-referencing.

TreeSize provides all details of file/folder distribution in seconds with a literal right click. It meets all QA/QC requirements for number processing for reference material archives.

Kudos to the folks at JAM whose system-integration and convenience-based GUI is an example many developers could learn from.
