Installation:

Copy/extract the TSC parent folder into your plugins. If you extracted the ~Documents folder into your plugins, too, it's highly recommended to keep it, but move it out of the Plugins folder.

It is highly recommended to run the cleanitol with the installer and remove any previous versions from your plugins.
In the ~Documents folder in the main ZIP in the Prop-Texture Catalogue Index and Cleanitol/ folder you will find the individual cleanitol scripts for the model packs of this compilation and by using either the newer nos.17's SC4 Cleanitol or the older BSC Cleanitol tool you can search and remove old and outdated versions of these files.
