Reason of Recover Files

when you delete files,the windows just make a sign on these deleted files. The Windows do not really deleted the information and the data of files, and the information and the data of deleted files would not be losted here. So we have a good chance to recover these files immediately.

But if you do not recover these deleted files, soon or later the data of these files would be covered with other new files. Then you would not get a correct files with Filerecoveryangel.

Discrete Files

If the parent directory of the deleted files and directories has been covered In NTFS, then these deleted files and directories can't been putted into the Drive's dirctory tree.So we put these files and directories into "Discrete files"

Unrecoverable Files

Sometimes we will get a incorrect files with the Filerecoveryangel. Because the whole data or the part of data of the deleted files had been covered with other data. Otherwise,In FAT system that including FAT32,FAT16,FAT12,the data of the file maybe stored in fragment.When we recover these deleted files In FAT,we just recover the data in rapid sequence, so we can not get the correct files.
