Re: dont have a data or delta folder

@Haz3l_2000  They should both be here by default:

C:\Program Files (x86)\Steam\steamapps\common\The Sims 4

By default, the Steam game library is always inside the Steam folder, as above.  So if you installed Steam on a different drive, look there.

Edit:  Since this thread is somewhat old now, I'll lock it here.  For anyone with a similar issue, please create a new thread.
