Apart from being a compression maniac, the unforgivable thing is that a Vendor is called that, and puts garbage on your hard drive. That's shameful. They don't compress almost anything: I'm not saying minify, but a simple gzip (zlib) included in Daz Studio.
They ignore anything.
A simple png to illustrate a duf, at 300Dpi and 4200X4200 pixels: And nothing happens. You install it and shut up. BECAUSE you do not know what you are getting into your computer: All fast and beautiful.
That is the Culture that exists now. (Or almost always, since the Neolithic ...)
The worst I've seen so far, and I've laughed out loud: A 54Mb Pdf on Linday's "Side Layered Messy Hair with dForce for Genesis 8 Female (s)". 54Mb, which once optimized, does not even reach 300Kb!
But, it doesn't end there: A "Tutorials" folder with 639Mb !!!! In video .mov format !!!
Does the problem scare?
Those are the PA professionals?
I have seen pdf's in documents of more than 100Mb.
I will be a psychopath, but there are more brave than me. ๐
That's why I say, before installing an IM00xxxxx, look at what there is: Be curious and dedicate.
