New Project Format

Juan Delgado - Apr 21, 2020

Hi CardCreators!

The new project format

The main target with the new format is to bring all the data that compose a project into a single project folder so you have everything in one place.

Here is a diagram showing a summary of the new project folder structure:

IMPORTANT: Please take note that the new project format CAN’T be opened in previous versions of the program.

When converting a legacy project:

  • A backup of the original .cc file will be created in the /backups/ folder.
  • The new project format folder will be created (if doesn’t exist) replacing the legacy .cc file.
  • All the older legacy backups will be copied into the /backups/ folder.
  • All images referenced will be COPIED to the /assets/images/ folder.
  • All the embeded images will be extracted and stored in the /assets/images_inline/ folder.

Here there are some highlights of the new format:

  • All the project data is stored as JSON files in the /data/ folder.
  • Each blueprint and each cardset is now a separate file.
  • All the backups of the project are in the /backups/ folder.
  • The project supports it’s own image gallery using folders inside the /assets/icon_gallery/ folder.
  • The new backup files are simple ZIP files containing all the JSON data files in /data/ folder.
  • All the timestamps for the backups, output or log files are in UTC.
  • When exporting a new set of files will be created in a new folder inside the /output/ folder.
  • The /output/, /backups/ and /temp/ folders can be safely deleted, the app will recreate them when needed.

For advanced users:

  • You should be able to copy easily blueprint JSON files between projects.
  • You can also copy cardset JSON files between projects, but make sure that the used blueprint GUID exists in the target project or it won’t work.
  • The new JSON format is more readable and programmer-friendly and thus it should be easier to manipulate either by hand or by a custom tool.
  • The new format is also very friendly with version-control systems like Git (in fact, some files like .gitignore and .gitattributes are autogenerated for you, you can safely modify or delete them if you want).

That’s all, we are working hard to bring more features in the following updates like the highly anticipated CSV/Excel support.
