How to find if a particular file is loaded by processes

Question

Can anyone please tell me in C# how to find a particular file is loaded by which processes? For example I want to check if C:	est.doc is loaded by which processes. Thanks Mushq

You can do it in a fashion with code such as the following which reads the window title of each process and looks to see if the file name is contained within it: using System; using System.Diagnostics; class Program { static void Main() { string search = @C:	est.doc; Process[] procs = Process.GetProcesses(); foreach(Process proc in procs) { if (proc.MainWindowTitle.IndexOf(search) > - 1) { Console.WriteLine({0} opened by {1} search proc.ProcessName); } } Console.ReadLine(); } } However in practice I think you'd need to search for not only 'c:	est.doc' but also 'test.doc' and 'test' because some applications don't show the full path name. The problem of course is that this could therefore throw up a test.doc in a different folder or test.txt perhaps.
