Re: Will my current sims 4 saves be deleted if I transfer new saves to my PC?
@namukoira Saves are only stored locally, on your computer, but can be transferred between computers without problems. So yes, you can transfer your saves. They're in Documents > Electronic Arts > The Sims 4 > saves.
There is one detail to be aware of though. Sims 4 gives save files different names starting with Slot_00000002.save , and counting up from there. So you probably have an 00000002 save on each computer. You'll need to renumber one of them so it doesn't conflict with, and possibly overwrite the other. Just find the highest-numbered save on your main computer and give the new save from your laptop the next number higher than that. These numbers are hexidecimal (0 to 9, a to f) and don't need to be in order; they just need to all be different and have exactly eight digits, includint the zeroes.
When you transfer content from one computer to the other, I would suggest zipping the files or folders first, to protect them. Right-click and select Send to > Compressed (zip) file, then right-click and select Extract when the .zip is on the new computer.
Longer-term, you can pass the saves folder back and forth between computers as much as you like, or upload it to a cloud storage service (for example Google Drive) and download it whenever you want to use the other computer.
By the way, your written English, at least, seems fine to me, and I'm a native speaker.
