Check what File Systems your Camera accepts first in it's manual/specifications if possible (maybe the manufacturers support site).
In my experience FAT32 is most likely expected and working for both Windows and your Camera.
RAW would mean unformatted regarding the media card (no File System on it yet).
(Right-click the media card in File Explorer, choose Format... from the Menu. Choose the File System in the Drop down list with File system and click the Start button.)
