FilePropertyEdit

With just several clicks, you can easily change the files attributes, including "create time", "modify time", "last access time", "read-only", "hidden", and "system", as well as modify their properties, such as document summary properties, photo's EXIF properties, MP3 ID3 tags (V1 and V2), and AVI RIFF Info tags.

With the cool file and folder browse feature and the drag and drop support, you can add a group of files and directories.
