I wanted an application to close files left open by crashing applications (one of my other projects was doing this). See, if a file is left open by an application when it quits, the Mac won't let anyone else touch it. The system must be rebooted in order to get access to the file again (or the file closed via devious means: OpenFileSpy).
This lead to a number of DAs. I decided to join the fray with an application. I also thought that just a file closer was a little boring. I wanted to make some better use of the Think C class library. So, I further included a detail window that will display info about the file's FCB.
If you think that this application needs anything more to make it complete, please let me know.
