Where are the saves for Pop Cap games located?
The location of the save games depends on your OS
For Windows XP they're in C:\Program Files\PopCap Games\[game]\Users.
Windows Vista and 7 they're in C:\ProgramData\PopCap Games\[game]\userdata.
If using Steam (Vista onwards) they're in C:\ProgramData\Steam\[game]'.
You might need to turn on hidden folders to see them.
For Mac OS X the folder is [username]/Library/Application Support/PopCap/[game].
Just copy that whole folder over and save it on the other computer.
