Re: Sims worlds transfers

@sian12071  In the 32-bit (Legacy Edition) version of Sims 4, saves are located here:

Documents > Electronic Arts > The Sims 4 Legacy Edition > saves

In 64-bit, they're in Documents > Electronic Arts > The Sims 4 > saves.  So just open the first location, copy whatever saves you want, and paste them into the second location.
