I've noticed since setting up & getting started again with DS, in this case 4.8, that when we save a Scene file, there's an option to Use Compression or not. Using Compression is the default setting, but what would happen if we don't? Is compressing it recommended or not?

I've noticed that with compression, a simple scene of just Victoria, clothes and a few props is just a couple Mb. I remember back when using 4.0 that that same very basic scene ran around 27+Mb. For me at least. But that was with the .daz format, not .duf. So what do you recommend? Especially when we add more people & environment & lighting to the scenes? Will the file size get massively huge or does .Duf simply work that much better?

I generally save as compressed file types,

It should make virtually no difference within DS but will save hard drive space. Saving uncompressed means you can manually edit .duf with a text editor, but it is possible to uncompress the .duf files manually with an unzipper if you do use compression.

Agreed, I used to save uncompressed so I could edit them if needed, but then I found out you can just unzip them, so might as well save space and compress...
