Technical FAQ

Q: I have recovered a file, but I cannot open it.

A: This may happen sometimes when using Data Recovery Wizard, especially for Microsoft Office files (Excel, Word, Power Point) or large files such as MPEG files. This may be caused by:

Damaged Files

After a file is deleted, it could be damaged by another file, overwriting, disk defragmentation, virus attack, or hacking activity. (Microsoft Office files are especially susceptible.)

Fragmented Files

Some large files are saved in discrete locations because they cannot secure contiguous hard disk space. When one of these files is deleted, recovery is very difficult. Even though the file's start location is available, the location information of other fragments is usually erased.
