I had to re-format my drive and re-install Windows XP.Prior to doing this, I copied folders I wanted to keep to a seperate disk. After I was done re-installling Windows, I placed the copied folders back onto drive c. When I try to open some of the folders, windows explorer gives an error message and shuts down.This also happen when I created an avi copy of a dvd I had. The program I used to create this copy placed the copy in a folder. When I tried to open that folder, windows explorer shut down again.Any ideas what is going on ?1 person got this answerI do too
