TWD: help trying moving game file

hi everyone.
so i just got my episode 4 and i have a bit of a problem.
i installed all the previous episodes on my c drive (actually a partition) (windows and system), but now ive got just 8 gbs of free space so i decided to move all the game files to another drive that has a lot of space in it.

the thing im not sure of is where are the save game files? and if i install all episodes one after another without playing and then import the save files, will it work?
