My judgement is that,
1. If a DBF(Foxpro)file emptied from Recycle Bin and after perform all HDD Scaning, the file should not be recovered from the HDD. But some softwares are able to recover the file. Is it Possible?
2. In the above file, if a date has been edited as prior date from the current date, it displays the edited date but the previous date remain same as an image and it could be seen easily by any well skilled software professional. Is it possible?
