Project | Open

With this you open an already existing project. You do not have to close the current project, it will be closed automatically, and if you have done any changes you will be asked whether they shall be saved. Note that even letting run the simulation means a changing because the position of the moveable elements can be changed.

Projects of TrySim are always saved in a directory. That means that you do not have to find a special project data but the directory in which your project is in.
