my folder become empty.........

today,when i wanted to reopen my folder again
suddenly it appear as empty folder
d reason y i wanna reopen my folder coz my computer hang d
so i save all d forms in my folder before i close it
after tat,i restart my computer again
coz long time din shut down my computer d
but,d most terrible thing happen was my folder become empty d
so i searched it in many place included hidden file
coz mayb wil save as hidden file if affected by virus
but,it still appear as empty folder
so wat can i do ??
i went to my new guilder place
n told her tat all my forms missing d after i restart my computer
so she came 2 my place n check wat happen 2 my computer
she also realised tat my folder really become empty d after she check in d folder properties
she also wonder wat alr happen to my computer d
but,i so lucky
coz i save 1 copy in drive d
but not d lastest copy
so i need 2 redo all d things tat i hv done 2day
at least,i no need 2 redo all d task again
coz it took me 1++ months 2 finish it
as conclusion...
