By selecting "Select Project Path" from the project menu of the
background window (or just pressing F2) you open the following dialog
window:
If you do not want to modify a saved state you can make a copy of the complete save-directory and use the copy (or another method is to specify a new, free directory immediately after loading the state).
Warning: Loading a previous state can already change the saved state (this can be the case if errors in the state or memory problems occur). This is because FUZZEKS tries to make the actual program state and saved state identical all the time.
If you want to make a backup of a state: Copy the complete directory contents
to a new directory. Later this new directory can be selected to load this
state or it can be copied back.
