I have a hard disk that a friend tried to copy the documents to another hard disk, and he said he sort of used ghosting or something like that so all same file extensions were grouped to the same folder, cannot open and funny file names like F001, f002 and so on and so forth, please can you help me recover my data, as i have very important datas inside.

Secondly there is a powerpoint presentation i was working on, all along when we've been practicing it, it was alright, but when it was shown on a projector, the text sort of shrinked together making it unreadable in some of the slides on both on the computer screen and on the projector, and later even after the projector was removed, it was still showing the computer, and the projector was tested with another presentation on another computer and it went alright.

Thanks Nairaland
