This guide breaks down:
-
How project groups and files are organized
-
The meaning behind different file extensions
-
Best practices for managing these files
1. Creating and Opening Project Groups
When you choose your Scan Mode, the software will prompt you to either:
-
Create a New Project Group, or
-
Open an Existing Project Group

If you create a new one, the software generates a parent project file at the location you choose.
If you open an existing one, a file explorer window allows you to select the correct project group file to load.
2. File Formats and Folder Organization
Standard Scan | Body Scan | Face Scan | |
Project Group | *.sln_nrap | *.sln_brap | *.sln_ir |
Project | *.nrap_prj | *.brap_prj | *.ir_prj |
If you have a file named
Shell2.sln_nrap, it's a Standard Scan project group. Inside the same folder, you might see several project files ending in .nrap_prj—each representing a specific project under that group.
3. Managing Multiple Projects in a Group
Icon | Function | Description |
![]() | New Project | Start a brand-new project within the group |
![]() | Open Project | Add a previously saved project* |
![]() | Remove Project | Temporarily take a project off the project tree (still saved locally and can be added back later) |
![]() | Delete Project | Permanently delete the project from both the software and the folder—it cannot be recovered |
4. Final Thoughts
Your scan data is saved within projects, which are housed inside a project group.
-
All projects show up in the project tree, while the actual files live in your local folder.
-
Every scan mode uses a specific file format for both project groups and project files.
-
You can add, import, remove, or delete projects within a group—just be careful with deletion, as it's permanent.
-
When importing, ensure the project’s scan mode and resolution match the current group’s settings.
By understanding this structure, you can keep your scanning projects organized and avoid any data loss or confusion during your work.
