I create a document on say 18 Jan 2016 revisit the document on say 1 Feb 2016, When I save the document it shows as the creation date of 18 Jan 2016. If I resave the dumnt it shows the document date as 18 Jan 2016. This is very annoying as when yoyu want to go to the latest version or visit a file as per date it is unclear which was the latest date you were working on the document/project. Is there some magical setting involved here??
If you are using windows explorer to view your files you may want to add some more columns.
Right click in your Windows Explorer where the red cross is in the Screencap and select what you want to see.
