It may be because I am paranoid but I back up all my Zip and Rar files as well as having a back up of my runtimes drive.  As my library lists has a date field I save all the files in folders related to the date (year and month) so they are easy to find.  It takes a few minutes extra each time I purchase something but I have had some items I have lostin the past and the web site I purchased from no longer exists so it is a small cost to pay.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
