i think my PC is crazy!!
it cannot rename all files!!!and besides that,it always has the type behind it!!
when i wanna rename it,it says:"If you change a files extension,the file may become unusable."
waht im susppose to do??!!! help!!
Even though the problem is over, I have that problem as well. And how I rename it, it's different then what Kasawa Lanford said. When I press yes on that question, the computer's right. It's unusable, I can't open the document! And the cause is, every document at the ending has the the word doc. (for 2003) docx. (2007) pptx (2007) etc.
You probably erase the doc, docx or pptx part that makes the computer thinks you're going to change the document into (for example, word, to power point) that's why there's a question saying open with what.
That's my guess. Since the problem's solved, I don't know if I should post this or not, but still it's for you all to know.
