FileDate Changer

This program works on Windows 95, 98, ME, NT, 2000, and XP. I’m not really sure if it’s going to work on Vista or not. I’ll see if I can find one that does! Anyway, it works without any installation and only needs Internet Explorer version 3 or above installed on the computer. Click Add Files, select the dates you want changed and click Change File Dates! Pretty simple. Note: Only works on files.

SetFileDate 2.0

This program has a prettier interface and allows you to multi-select from an explorer type interface rather than having to add files one by one. You can also change the dates of folders using SetFileDate. It’s very small and very easy to use!

eXpress Timestamp Toucher

The difference between this program and the others is that eXpress TT allows you to change the date and time for a file or folders AND optionally all sub-folders. This can prove to be very useful if you need to change the date and time for all files and folders under a specific folder. You can change the creation time, modified time, and last access time.
