TDE is a program to convert your old floppies into MSA disk images. Yes, I know there are excellent apps already out like Jay MSA and Magic Shadow Archiver but TDE works at a technically lower level and therefore has far more success with those crusty old floppies. In fact, even if TDE fails on a dead part of a disk, it still offers the option to save a good image thus you're able to rescue the remainder. Such an excellent and essential utility.
Of course, the mighty D-Bug has the latest release of TDE to download so waste no more time and go grab it!
