i've set an exact copy of the source folder and this has deleted a file ( orphan ) in the destination folder. How can i recover the deleted file ?
Thank you for your help.
this depends on what file-system you use.
any file recovery software that understands the file-system you use will help you recover the file.
depending on how full the disk is and how much you used it after deleting the file it might still be possible to recover it
please note that any software that writes to the disk will reduce the probability of you recovering your files,
so maybe make a full backup of the entire disk(including unused sectors, since this is where your file is)
You can use Recuva to recover the deleted file for free. It's a freeware.
Personally, I use this one: http://www.kvisoft.com/data-recovery/
