It’s still a bit disingenuous for them to have that policy. The storage costs would be trivial and so this sounds like nothing more than a way to gouge customers who might lose their copy.From the UIL Store website -
"NOTE: You (the purchaser) must save all digital downloads onto your computer or storage device. With each purchase you are granted access to digital items for 1 year or 5 downloads, whichever occurs first. The UIL can not reverse that counter, so you (the purchaser) are responsible for saving these digital files."
So. yes, I'm sure the 1 year access refers to how long you will be able to download the file.
