WhatsOpen - eject those Stubborn Volumes from your Mac

Every once in a while I will have a disk image or a disk volume open and I will be unable to eject the volume because some application is using a file on the volume and the OS blocks you from ejecting it. The solution of course is to find the application that is using the file and close it so you can eject the volume.

Sometimes this is easy because maybe you only have one application open, but what if you used multiple files in multiple applications. Finding the culprit might include shutting down all your applications until you find the right one.

There is an easy solution to this problem and it’s called WhatsOpen. All you have to do is right click the volume and select “list files” and WhatsOpen will make a list of all the files that are being used by applications on the volume. From there WhatsOpen gives you some tools to close those apps and get the volume ejected.

I know this seems trivial but it really comes in handy when you want to eject a volume without closing all your applications. Sometimes the finder is the one using files which is hard to track down without an application like this.
