Problem - file with a size but no content?

today when I working on my site and writing in a .css file suddenly my computer shutdown when I turn it on and open the .css file I working on it was empty but file size of the file was like it is full. How I can restore the content of the f开发者_如何学Cile? Please help, I worked on this file almost a week.

the filesize could just be old cached information, if you're using windows press F5 and if the filesize change then your file is gone, then you should ask yourself why didnt you save your css through out the proccess if you did then there's a chance you could retrieve it, search through your temp folders for any css file that might be the file you lost, there is also a ocean of application that helps you retrieve lost documents use google and you'll sure find something

p.s. what happens if you open that file with notepad
