A .dat file whose contents are encrypted with a simple XOR key. WeChat stores the images from its chats this way, and some other apps do the same with sound and documents. Filestar finds the key and restores the original file, such as a JPEG, PNG or GIF.
An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
