@hlnbrg When you upload anything to the exchange for others to download, any cc involved is only supposed to accompany the file if the cc is still in your DCBackup folder. If it is, it should upload automatically too.
However, I would strongly recommend against including cc in any item you want to share with others. First of all, players sometimes have trouble downloading (or uploading) files containing cc, and it seems like some cc items give more trouble than others. It wouldn't be fun for you to have to go through an entire world looking for the one decor object that's preventing your world from uploading properly. And this has been known to happen.
More importantly, though, most players don't want cc in anything they download. Bad cc has been a scourge since the beginning of TS3, and it can be so hard to remove that sometimes the only option is to rebuild the entire game folder from scratch. For this reason, many people wouldn't download anything with cc in it if they knew it was there in advance. Some people build lots and create sims for the exchange in a separate, "clean" game folder (i.e. the content-free one that spawns when you pull your existing one out of Documents), just to help protect the rest of the community.
There are tools to detect bad cc (you can google Delphy's Dashboard and Custard), and it's certainly the responsibility of the person doing the downloading to check any player-made content for unwanted files, but it's still considered bad manners to include cc without telling anyone. If you could, you'd be doing everyone else a favor if you left out the cc. At the very least, you could list it and have it available for separate download, so individual users could decide for themselves.
I'm sorry if this sounds a bit harsh, but imagine the frustration of someone who realizes that the only way to remove an unwanted cc item is to start from scratch. Here's one example of bad cc that's still circulating years after it was first identified. Every time we think it's gone, the exchange is reinfected by some unwitting player who uploads a file with this item along for the ride.
