Changing the file creation date does not work

Question

I'm using the following to change the creation date of a text file:

using System.IO;  ... DateTime newCreate = new DateTime(year, month, day, hour, minutes, seconds); File.SetCreationTime("changemydate.txt", newCreate); 

However this doesn't do anything. There is no error message, yet it doesn't change the date of the file at all.

I tried this in a dropbox folder as well as in a random folder without success

The DateTime newCreate object seems to be correct though.

It would be great if somebody could point me to an idea...

Answer 1

Actually, each file has three different times:

1. Creation time
2. Last access time
3. Last write time (that's shown in Explorer and other file managers as "File Date")

To modify these times you can use

File.SetCreationTime(path, time); File.SetLastWriteTime(path, time); File.SetLastAccessTime(path, time); 

respectively.

It seems, that if you want to change file date as it shown in file manager (e.g. Explorer) you should try something like that:

String path = @"changemydate.txt";                 DateTime time = new DateTime(year, month, day, hour, minutes, seconds);   if (File.Exists(path))     File.SetLastWriteTime(path, time);
