Greenfish DataMiner is a tool that lets you recover all sorts of data from a damaged CD or DVD or one that you have accidentally recorded over (in case the disc is rewritable). Using the app is as simple as double-clicking on the .exe file and, without installing, selecting the type of disc that you want to recover information from. The program will quickly list all the files available to be recovered, as well as their size and extension, so that you can find the ones that you're looking for more easily. Greenfish DataMiner can be useful in specific cases, so having it saved just in case (remember that it doesn't have to be installed) is an excellent idea.
