Hi All,

I have been working on a project in Codesys V3.5 SP14 Patch 3.

When I last saved my project it was saved as a '0 File' (see attached), and is no longer able to be opened in Codesys. I really do not want to start the project all over again! Can anyone tell me how to open/recover this file?

Furthermore, if anyone knows why this is happening and how to stop it, I would really appreciate it!

Best regards,

John

Hello John,

you should be able to rename your project in the normal windows explorer and make it end with .project

Hi Marcel,

Thank you for taking the time to answer my question

Unfortunately, when I add '.project' to the end of the file name in windows file explorer, it changes it to 'myapplication.project.0' so Codesys still won't recognise the file when trying to open it in the correct V3.5 service package.

Am I doing something wrong when I change the file name?

I have since started the Codesys project again and it is now running successfully, but I would still be interested in how to recover from this issue. I was lucky this time that it was very early in development!

Best regards,

John

This is still causing problems - does any one know how to resolve this issue?

Once it is saved a a '0 File' I cannot recover my project!!!!

Still the same solution.

Maybe you need to tell the explorer to display the filename with the extension and then you can change the file extension.

Google for "How do you display filename extensions?" and then try it again.

Best regards,
Marcel
