Before you purchase a program to undelete files you should first understand what a deleted file actually is. When you create a file your computer magnetically rights digital code onto a small portion of your computer’s hard disk drive. That information which contains your digital photographs, Microsoft Word documents, or your favorite computer game is written on to a specific portion of your hard disk drive.
Deleting that file or application does not remove the written information. Instead it simply marks the directory area of that file as now available for new data. There is virtually no such thing as file erasing. In fact even programs specifically designed for file shredding cannot magnetically remove the inherent older file content. All these programs can do it is write new content over those sectors. Because the most recent layer of content is easily read it becomes a new file. You can undelete files simply by sending in a scan from a data recovery tool to read the original information and recreate the file structure. This undelete process includes attaching of the original file name and allows you to copy that original file information to a separate location.
