<… will they be overwritten? > Not silly at all!
Once transferring files to your computer, the data becomes "computer managed". Consequently, the computer will not accept two or more files with the same name at the same place. For example, if there is already a file named DSC 002 on your desktop, another one will not be accepted as is. Your computer will alarm you: 1• …this name already exist at this destination. Do you want to replace it with the new one? or 2• giving you the options to either "replace", "keep both" (in which case the com- puter will add a character to the new one), or "stop". I'm on Mac, don't know about Window, but there should be something like that.
I adopted, for the sake of clarity and safety, a simple system to name the folder that contains my RAW files.
My cameras use CF cards. These CF cards bare the name of the camera they are used with (in my case Nikon D3X, in your case D50 and D7100 for example). On these cards there is a folder that contains my RAW files. This folder is named also with a designation that tells me it may come only from that card (card #8: 888D3X) as that card is only used with this camera. I always copy this folder to my computer and back it up before reformatting the card in the camera, ready to shoot again.
The individual files may have any name (D3X_1234.NEF) and, if another one already exist at a given destination, since the new incoming files are in their own folder, there is never any problem. That is, if I did not forget to rename the previous folder with the event name or the subject name before I copied it to my archive and made a back up.
