People do know how to zip properly, just the people that install them don't know that the add-ons folder in the zip doesn't go in your already existing add-ons folder. It goes in the blockland folder and you replace the add-ons folder. Sigh.
But than doesn't that mean that you are unzipping it incorrectly?
For example, @ Satan:
You said you got Add-Ons/shapes/add-ons/shapes/add-ons/shapes/file.dts
So doesn't that mean that you unzipped it into your addons folder, which already had another one in it, probably from a previous attempt to unzip something, and than you unzipped it in there.
So wouldn't the problem here be with people not knowing where to unzip things?
The posts here sort of mislead the whole topic.
