In earlier versions of EXScan, working directly with individual projects was the standard. However, with newer releases of the software, a new structure called a Workspace or Work has been introduced.
A Work acts as a container or “parent” that holds multiple scan projects. While this is a more organized system, it can lead to confusion when trying to open older project files.
If your existing project is saved in formats like .rap_prj, .hd_prj, or .fix_prj, you might notice that they don’t appear when you try to open them through ‘Open Work’—which only recognizes .sln_rap, .sln_hd, or .sln_fix files.
Here’s a simple workaround to open your old projects:
Determine the Scan Mode Used:
-
.rap_prj= Handheld Rapid Scan -
.hd_prj= Handheld HD Scan -
.fix_prj= Fixed Scan
-
Create a New Work:
-
In EXScan, start a new Work.
-
Choose a save location and give your Work a name.

-
Once Inside the New Work Interface:
You have two ways to open your old project:
-
Click the ‘Project’ icon on the right side and choose ‘Project’ again.
-
OR go to the ‘Work’ section on the left and click ‘Open Project’.

-
Locate and Open Your Old Project File:
-
Use the file browser to find your
.rap_prj,.hd_prj, or.fix_prjfile. -
Select and open it—it will load within the new Work.
-

Important:
Make sure all associated project files are stored in the same directory. Without them, the project may not import properly.
