assigning random creation dates to files sardinian_guy <guest[ at ]unknown-email.com> 12/30/2008 3:29:49 PM Hallo guys and happy new year to everybody. :D Sometimes to make tests I need to assign different creation dates between a specific range to my files. I'm looking for a way to do it with powershell. I found this article 'Generate Random Dates in PowerShell « saadware' (http://blog.saadware.com/2008/06/12/generate-random-dates-in-powershell/) but i don't know how to apply this code to each file within a folder. Thanks in advance. -- sardinian_guy

However I made some proof and the dates don't seem so random. If I have few files, the same date occurs for several files. Is it the right behaviour or is it possible to have something more "randomly"? Thanks again -- sardinian_guy
