Reply To: Did you know? (Two types of templates)

I think there are two types of InDesign files.

A template opens by default as an Untitled copy; a regular file opens by default as 'original'.

What's the difference between a template and a regular document? The file extension. If you change it outside of ID, ID will not handle it anything special other than doing its default action on opening.

Why do I keep saying “by default”? Well … Press Ctrl(/Cmd)+O to open a file. If the file type is “All Readable Files”, you will see both templates and normal files. At the bottom of that dialog, you see “Open As”, with the radio button “Normal” checked — that's so ID will do the default action, depending on the file extension.

If you want to open a copy of a regular file, choose “Copy”; if you want to open a template for editing, choose “Original”.
