Not very. If the application was an MDI app, not at all. What the theory would be is to check the title bar of all open applications to see if the file you were searching for is in use by its presence in the title bar. However, if the application is an MDI application, the document may be in use, but not the current document being used. In this case the file would be in use, but wouldn't be reflected in the title bar. Simplest is probably to use FOPEN() to open the file on a low level. If the result is -1 it's in use.
