Recovered files

[genemb]

I recovered files with a recovery utility. How do I get them to become a complete File program again,there all broken up into file ext. When I double click on them wins says it doesn't recognize these file ext. I go to the link that Wins gives and sure enough the company name is there ,but that doesn't tell me ,from what I can see how to get them all back together to become a complete file that Wins recognizes. This is a program :Autocad 2005 LT that I am trying to recover off the HDD. I don't have the original program Cd-Rom because the one I have has a unreadable area on it and I come up with the error 1305 when I am installing it about 60% of the way thru the install .

Info on this dilemna would be appreciated ,Thanks
