If you lose or delete without wanting to an important file or something you might need later...don`t start pulling your hair out. DataRecovery will save you. The program comletely analyzes your hard drive (it supports NTFS and FAT format file systems) and identifies all deleted and recoverable files, allowing you to choose those you prefer to recover. This is possible because Windows doesn`t physically delete files, it just marks them as empty space on the hard drive, allowing you to write over this space when you need to. For this reason it is easier to recover a file when the least time possible has passed since you deleted it.
