All projects are saved in the bibisco projects directory (Where is my projects directory?).
The projects directory has this structure:
projects directory (purple arrow): is the projects directory you choose.
_internal_bibisco2_projects_db_ (green arrow) is the parent directory of all projects.
backup (red arrow): is a backup directory where, every time bibisco starts, every project is exported as archive (file with extension .bibisco2). Each archive file has a significant name: title of the project (red line) _ identifier of the project (blue line) _ timestamp of backup in the form YEAR_MONTH_DAY_HOURS_MINUTES_SECONDS (green line).
other directories (blue arrow): specific project directory that contains a JSON file (red arrow) that is the project file and images directory (blue arrow) that contains the images of the project.
