Sims 2 Pack Clean Installer...overwriting files?

[riverrat4life]

I just downloaded the sims 2 and all expansion packs up to seasons. My question is when using the 2 pack installer to install files, sometimes it says a file already exists, do I want to overwrite it? What does this mean and do I overwrite it? Please help me with this, thank you.

It means that the file already exists in the folder you are writting to. I generally say "yes". However, if what you are installing is likely to be an older file, you may wish to rename it (I think that's an option), say no, or install in a different folder for a closer look before deciding what to do.
