Where is the saved games folder?

[WindexGlow]

how about mandrivalinux?

~/.frictionalgames/Penumbra\ Overture/Episode1/save/

thanks! now is there any reason why we can't save all areas? why do they have to remove the older ones as you go along?

Those save files are quite large, every single time you move an object, no matter how small, it saves where it is.
Open a door? It will save the exact position it is in.
