Accidentally Erased Some Photos?
If you’ve ever erased photos by mistake, or lost files when a program or computer crashed, don’t despair.
A common misconception is that the data is actually destroyed when you delete or erase a file. What really happens is that a tiny bit of information which points to the location of the file is the only thing actually erased. Every file and folder on your device has this “pointer”, which is saved in a special section and is used find the file or folder when it is needed. By erasing the pointer for a file, the file itself becomes invisible and looks like empty space. Eventually, thedevice will write new data over the area where the old file is located – so your chances of fully recovering a file diminish the longer you wait after you deleted the file since the probability that the file has been overwritten increases.
There are several hard disk utilities that you can find on the Internet that allow you to recover “deleted” files. What these utilities do is search for data on the hard drive that does not have corresponding pointer information and present you with a list of these files. Your chances of fully recovering a file diminish the longer you wait after you deleted the file since the probability that the file has been overwritten increases. Sometimes you can recover portions of a file that has not been completely overwritten.
