The folding process may be complex and is composed of many back and forth steps. Therefore, it is useful to be able to review an already executed sequence of folds. The folder has a batch language for this purpose, and every folding command is logged in a special file 1.

Such a file may be read by the folder and executed again in a debugger-like manner.

The syntax of the batch commands is documented and available (see the Batch Language Reference Manual). The batch files are readable and editable, but this exercise is not advised for the first time users.
