How to clear incorrect file association

[pbw]

In an open xlsx Excel file, I opened the _rels/.rels file as a text file. It's not; it's an xml file. However, now, whenever I open this file, it assumes it's a txt file. How do I clear this erroneous association?

I'm using 11.0 on Mac Snow Leopard.

Hello,

When you opened the file as "text", Oxygen saved this association between the file and the "text" content type. Now each time it will be reopened as "text".
If you want to change this association you can add your ".rels" file to your project and after invoking the contextual menu on it from the Project view choose "Open as..." action. If you do not use a project you can create a new project and perform the same steps.

Regards,
Iulian.
