# Preprocessor editing

Preprocessor editing can be accessed from either the main screen of the preprocessors, or from a preprocessor detail.  

Preprocessor editing allows for the modification of all the information entered when creating the preprocessor, with the exception of the files that are a direct part of the latter. In the Edit screen we are allowed to select the executable file from the list of preprocessors stored in the system.

We must contact the system administrator in order to carry out replacement or deletion of files related to the preprocessor. The system administrator can take the necessary actions and will have to check the process.

In the configuration of the preprocessor parameter, the system will show a form with the same data and editing conditions as in the creation.
