I want to prevent the user from encrypting or decrypting the file if it's open (i.e. the file is open in Word). I would like to display a dialog box that says something like "myWord Doc.docx is open. Please close it and continue." I've found the ability to find running applications and I've found commentary that says what I'm asking for is not possible. I couldn't find anything in NSWorkspace or NSFileManager to help unless there's a file attribute I don't know about that can tell me. Any ideas?

If the feature is only required to target a limited number of applications and they are scriptable you could use AppleEvents (or AppleScript or the ScriptingBridge framework) to query the application document list. This would give access to files open at the application level rather than files open at the system library level.
If the feature is to be wholly generic however this is a non starter.
