Can delete files in C:/Documents/DAZ 3D/Studio/My Daz Connect Library/data/cloud,beacuse it is very large. I don't know when they did be in this folder. Thanks.

I would check for duplicate files elsewhere before deleting anything. I have found this is the case on my system, the only folder would not touch at the moment is the meta folder. It seems to update every time DS is opened.

Those are your Connect installs.

The meta folder will update every session only if you have told DS to always log-in - if you don't use Connect then there's no point in doing so.

Thanks and good health..
