In DOS, all that was changed was the first character in the filename . This means that a recovery programme can look in the directory for evidence of deleted files . When it finds one, it can get the starting location of the file, and the size . It might be able to recover a file from this information . If the area hasn't had a new file put in it, and if the original file was not stored in a number of chunks ("fragmented") . After the dreadful moment when you realise: "No, I was not sure", it's important not to use the computer . An immediate power off is indicated . Windows is always writing to the disk . Any write can destroy what you want . It's equally important for recovery programmes not to write recovered data to the same disk partition . They get the OS to write their output, and the OS knows that the areas used by deleted files are free . :D |
