I experienced this kind of situation few days before. Situation:Each directory was hidden,and a new made same name file shortcut were made.If i click into the shortcut, the directory sometimes correctly showed and sometimes not. By checking ,i found a directory shortcut I've never seen called '8585485', and it contained a .exe file. Solution:Backup ur file immediately as u can, then, Win vista/7:execute cmd -> cd %PUBLIC% ->REG DELETE HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Run /v "Java Update Manager" /f ->REBOOT ur PC ->Execute cmd -> cd %PUBLIC% -> del /f /s /q /a:s jusched.exe} -> X: (X=ur n9's drive) -> cd \8585485 -> del /f /s /q /a:s *.exe -> cd \ -> attrib -R -A -S -H /S /R Finally,remove the .ink file urself. This is my experience,it is annoying to clear device twice before i know the solution.
