stm8s cannot edit SPL file in project

[sebbs]

As the subject mentions, I have a project in ST Visual Develop and I added the SPL files to the same location as the project. Once I add the files to the project and try to uncomment my specific stm8 it simply doesnt let me. I try editing the other files like the stm8_adc1.h file and I cannot edit it either. This is only when I add them to the project. How can I fix this?

Thank you in advance.

I figured it out, you have to go to the folder they are in (instead of doing individual) right click and go to properties and deselect "read-only" and click apply then okay.
