Upgrade Policy (When are Upgrades Free?)


The product upgrade policy is as follows:


Minor version upgrades are free

Major version upgrades are subject to an upgrade fee


Duplicate File Detective has a three-part version number (for example, "5.1.21"), with the first of these numbers representing the major version number. Minor version upgrades are those in which the major product version number remains the same. Major version upgrades are those in which the major version number is higher than that for which you are currently licensed.


The full Duplicate File Detective version number is always displayed in the main window title bar, or within the About dialog window.


Major version upgrade fees are outlined within the ordering section of our product website.
