Portable Durable Copy is a useful application which allows you to copy files, enabling you to read most part of data from those files which contain damaged sectors.
For clear idea we are giving here two examples. For instance, you have got a CD or DVD with a certain interesting movie. You wish to watch this movie but can't do it because the disk contains unreadable sectors, and it is read badly.
At that, your computer either reads this disk not properly or can't read only some sectors in it. At a time when broken sectors draw near, then depiction begins to be very unsteady. Surely, your pleasure from viewing the movie disappears.
You wish you were able to copy this movie to your computer' hard disk and to watch the movie from there but, for example, some files somewhere in the middle of this disk are not read totally. In this case, the Portable Durable Copy would be useful for you.
Moreover, all programs which usually work with broken files refuse to work with your backup copies because of these files are physically damaged. Again, the Durable Copy can help you because it is destined for reading physically damaged files precisely.
