Default indd file gone and new docs open with no Para. styles

Hi,

When creating a new indd file in ID CS6, a set of para tags etc were automatically loaded into the new doc.Today I opened a new file and it opened with only a basic para tag. I know that years ago I created a sort of default file that included all the setting that I wanted to default to for any new project, saved it where Adobe told me to and named it what Adobe told me ID would look for when creating new docs.

I thought it might be default.indd but no soap.

Can anyone tell me the correct name and folder where this file should be kept.

Thanks very much

Jon
