We have got the updates for you regarding the Ticket METADATANET-2837.
The Date created, Date modified and Date accessed properties (that appear under File section in the Windows Properties as well) of a file (image/document) have nothing to do with document’s content, instead, they are just common attributes of any file and folder stored in the file system. When you copy a file, the properties change, despite the fact, the content remains the same. That’s why it’s not included in the metadata properties that are attached to the document.
In case you still want to update these dates, you can easily do it using the standard classes of .NET framework (as shown in the following code snippets).
//File and FileInfo classes belong to the System.IO namespace
DateTime newValue = new DateTime(2085, 8, 15);
const string path = @"D:\test.docx";
FileInfo fileInfo = new FileInfo(path);
fileInfo.CreationTime = newValue;
fileInfo.LastWriteTime = newValue;
fileInfo.LastAccessTime = newValue;
Hope it helps.
