There is good and simple way to check history of your document, last version of InDesign used while saving file, but also version used to create file for the first time. Also, you can find a little bit more about your application like for example number of plugins installed, versions of some core components and other. But, that’s not something you will need very often.
Then, what’s so great about this? Great thing is that you can see plug-ins used in document and also missing ones! Another thing you can find out is which system (PC or Mac) was used to save the file and how many times file was saved! (this is not true for documents loaded in newer version of InDesign) So, where we can find that info?
It’s really easy. Simply go to Help menu and Ctrl (PC) / Command (Mac) + Click on About InDesign… menu item and info dialog will show up immediately.
This is a really good way to check your document if something goes wrong.
