Fix the Parent Folder Date Modification Issue
In Microsoft Word and PowerPoint 2016 for Macintosh, if a document is opened, even if it is not modified, the modification date of the parent folder changes, even though the modification date of the file itself does not.
This also happens with Excel 2016, if a .xlsx document is opened, but not if a .xls document is opened.
This does not happen with Word 2011 and PowerPoint 2011 for Macintosh, though Excel 2011 has the some behavior as Excel 2016.
It would be great if Microsoft could fix this issue. It also happens in Windows.
