Une option du fichier de configuration se nomme save.recent. Il suffit de mettre sa valeur à 1 et Scite se souviendra des fichiers ouverts.
save.recent=1
save.session=1
Voici un extrait de l'aide :
Setting save.recent causes the most recently used files list to be saved on exit in a file and reloaded at start up. For GTK+, the file is called ".SciTE.recent" and is located in the directory given by the SciTE_HOME environment variable and if that is not set, the value of the HOME environment variable and if that is not set the top level directory. For Windows, the file is called SciTE.recent and is located in the directory given by the SciTE_HOME environment variable and if that is not set, the value of the USERPROFILE environment variable and if that is not set the directory of the SciTE executable.
If you set "save.session=1", current session will be automatically saved to a file "SciTE.session" on Windows and ".SciTE.session" on GTK+ located at the same place as "SciTE.recent" file. When you start SciTE next time the last session will be automatically loaded.
