winxp/truncated files

[greenlite]

Have winxp pro and while i had a file open that held blk and wht photos of an ongoing collection of people and ww2 planes,there was a power surge and while system did bootup,it went thru a series of checking file system and somewhere along the way,i noticed it said something about "truncating files" infortunately,i didnt get a chance to see exactly what it was doing since it went by fast. went back to my folder,since i wasnt retouching anything,just browsing,id figured theyd be ok. they are gone,all,and to make matters worse they are not name but numbered.search did not return any of them. im sorry i know this is long, so question is what the heck is truncated and how could i un do this? any help will be highly appreciated
