Upgrade Policy (When are Upgrades Free?)


The FolderSizes product upgrade policy is as follows:


Minor version upgrades are free

Major version upgrades are subject to an upgrade fee


FolderSizes has a three-part version number (for example, "5.0.40"), 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 FolderSizes 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 FolderSizes product website. If you have any questions regarding this policy, please contact us at
