My sister and I have different windows users and when she downloaded Myst, we played on her account, but now I want those saves on my user and once I go to her program files in computer and in the revelations folder, once I enter the save folder it says its empty . Now I open myst and the save files are there

I dont understand where I can find where the saves are, If i can find them I can get them to me.

PLEASE HELP

The save files are in the "myst4-revelation savegames" folder in "My Documents".
