how can i protect my folder with my private things?
Without getting uploaded by other devices or coppied straight from my laptop ?

I know there are plenty of ways to lock and hide folders. Plenty of Windows options could help and even 3rd party programs. Real protection though? Leave it on a flash drive.

As the others have said above is a good idea, also try making sure there are no auto file uploading programs to a file storing cloud like a client for mega.nz for example, the computer should be clean to make sure no one with a remote administration tool doesn't have access to copy the documents and just encrypt a USB with Veracrypt and access it through a Linux computer would be your best option.

Maybe create a new volume on your disk and enable BitLocker on it to require a password when opening. That's how I would do it.

You can always pgp it and keep the key on a usb stick
