0	The short answer is NO. You have to try/catch the file operation. public bool FileIsLocked(string strFullFileName) { bool blnReturn = false; System.IO.FileStream fs; try { fs = System.IO.File.Open(strFullFileName, IO.FileMode.OpenOrCreate, IO.FileAccess.Read, IO.FileShare.None); fs.Close(); } catch (System.IO.IOException ex) { blnReturn = true; } return blnReturn; } Himanshu Manjarawala Sr. Software Engineer@AutomationAnywhere http://fieredotnet.wordpress.com/ Oswaldlily, if this helps please login to Mark As Answer. \| Alert Moderator

public bool FileIsLocked(string strFullFileName) {

bool blnReturn = false;

System.IO.FileStream fs;

try {

fs = System.IO.File.Open(strFullFileName,

IO.FileMode.OpenOrCreate, IO.FileAccess.Read, IO.FileShare.None);

fs.Close();

}

catch (System.IO.IOException ex) {

blnReturn = true;

}

return blnReturn;

}
