Really interesting, knowing if a file is already in use by another application via an api instead of trying to open it and manage the error (without knowing "who" is blocking it anyway) is very useful in some scenarios.

This might be slow and resource intensive, depending on situation. 

My idea of pseudocode pattern would be something like.
 

try
  FileOperations(LFileName);
except
  on E: Exception do
  begin
     ...
     if GetProcessReservingFile(LFileName, LProcessFileName) then 
       LErrorMessage := LErrorMessage + ' File is being used by ' + LProcessFileName;
     ...
  end;
end;

 

But everything depends on the situation.  Anyhow, user most likely would like  to know what app has the file is opened.

FWIW: There's also IFileIsInUse. E.g. delphi - Checking if the file is in use and by which application? - Stack Overflow.

But it only works for apps that support it.

Quite limited but interesting still.
