Ever want to change the date and time stamp on a file in Windows? Touch makes it easy. When you install it, this free tool adds a new property page to every file's Properties tab. Just highlight one or more files in an Explorer window and select "Properties" from the right-click menu.
Type in the desired time and use the calendar control to set the date. Check the boxes on the fields you want to update: Created, Last Accessed, and/or Last Written. Press the "Now" button to give the file(s) the current date and time.
