Re: SIMS 3 64 BIT ISSUE: Game files upload/download during gameplay

@AshleyGamer124  Are your files uploading to iCloud?  If so, you can disable iCloud's automatic syncing of Documents.  This guide is for a different issue, but the relevant settings are the same:

When you change the settings, it's possible that iCloud will remove the Sims 3 folder from your local version of Documents, so double-check and copy it back if necessary.
