Google Drive Sharing – How to Tell if People Have Opened a Shared Document

There is no such option in Google Docs as such . But there may be possibility of using GreeseMonkey Scripts or third-party browser extensions for doing so.

But there the problem would be that we have to match the file-name and size of each newly uploaded file with all the existing once, but Google Docs does not shows the file sizes of individual files in anyway.

The third-party extension would have to download the all the files to make it possible - which is not practical and also not possible because Google Docs sometimes converts the uploaded files into it's own format - screws the formatting and file size also alters.

So, basically not possible.

When you click on an event on the calendar, it will show who created the event on the calendar. The different colors are only applicable to differentiate between events from different calendars.
