Changing the date of a file

[Frankiz]

Hi,

I try to change the date of a file:

MsgBox FileSystem.FileDateTime("C:\temp\test.txt")

No problem! I can see the date of the file!

FileSystem.FileDateTime("C:\temp\test.txt") = Now - 3

But why doesn't that work! VB says "Object Required"

Thanks for your help!
