hi,

this expected process "context" running executable file regardless of data files opened process...

knowing trying (what wiht info ?)

see if tool such as http://technet.microsoft.com/en-us/sysinternals/bb896655 shows need. have low level api (this tool seems based on "object management" api) that allows list opened files (or wmi maybe)

so link gave seems use object management api. not sure how used it. if tried list files each process perhaps list files , keep in interested in case quicker...

or else please explicit issue (is issue looking @ processes rather files returned detectopenfiles ? understanding output .exe files, variable them ?)

please mark whatever response solved issue thread marked "answered".
