Quote - The only issue I see with a download manager, is that if the produst is no longer sold you wont get it back anyway. They are great if the product will be there at the time you need it to be, but that is a big if...

My Runtimes go as far back as Poser 4, and many of the things in them are no longer available. I also have many characters, clothes, and props that I created myself.

Backing them up is the only way to ensure that they don't turn into vaporwear.

My Runtimes are mirrored onto 5 machines.

The DAZ Install Manager doesn't have to delete the zip when it's done - in fact i think leaving them is the default state. As long as the zip is there it will install the product, even if it is no longer available - and i should add that all products should remain available to download for purchasers, even if they are pulled from the store or moved to another store (I still have some of Traveler's V1 outfits, with RenaPD's textures, showing in DIM).
