Hello Mister von Bernhard
Please accept my apologies for the hereunder certainly stupid question.
In windows 10, when activating the program 1130b and trying to change date and time on a specific file, and when done I push on the button "Applying", then I see and update in the Windows explorer which refreshes  the page and then, the file always have disappeared from the folder list. 
Where is it?
Thank you very much for your answer.
Nathan.
