You can try moving your userprofile folder or just the documents folder with
one of these methods.
There's also a property SaveGameFolderName in the registry under
HKEY_CURRENT_USER\Software\Telltale Games\WalkingDead101.exe
that you could try to rename, if just the
%userprofile%\Documents\Telltale Games\The Walking Dead
folder is not accessible.
All of this i have not tested, but the first one should work, the second one might.
Edit
Just made a quick successful test with the registry value. Absolute Paths don't work, so you can't choose a different drive. But you can use relative Paths like ..\..\The Walking Dead to move it further up your profile.
