Supports both files and folders

Despite its name, Change Folder Date offers you the possibility to tamper with the timestamps of files and folders, meaning it does not restrict you to directories. However, you cannot have both types of items simultaneously in the list, you need to take turns processing only files, then moving on to folders.
On the downside, the only way to add these to the main window is to manually browse to their location, since drag and drop actions are not supported.

Modify several types of timestamps

Once you have set up the source list, you need to choose the type of attributes you want to alter. Change Folder Date can be used to modify the exact creation time and date, last write time and last access time.
For each of these parameters, you can either enter the current time and date, or you can navigate to certain values, depending on your needs.
