If you are running System 7.5, when you first attempt to open a file created by an application you do not have on your hard drive, the Macintosh Easy Open window appears. Macintosh Easy Open provides a list of applications on your hard drive from which you can select an application with which to attempt to open the file.

If you accidentally select the wrong application in the initial Macintosh Easy Open window, each successive time you attempt to open that file or other files with the same creator, the wrong application is launched. Fortunately, there a way to reset this so that the wrong application will not be launched.

After selecting the wrong application to open a particular file, you need to delete Macintosh Easy Open's preference file, or the wrong application remains associated with that file, and files that have the same creator type as that file.

To delete the preference file and rebuild the desktop, follow these steps:

Step 1

Open the Macintosh Easy Open control panel, and click the Delete Preferences button.

Step 2

After deleting the preference file, you will need to rebuild your desktop file this way:

Step a

Restart your Macintosh and hold down the Space Bar until the Extensions Manager control panel opens.

Step b

Use the pull down menu in the Extensions Manager to choose "All Off"

Step c

Scroll down to the Control Panels section of the Extensions Manager window and click the Macintosh Easy Open item to put a check mark by it.

Step d

Close the Extensions Manager window by clicking on the close box in the upper left corner.

Step e

Immediately hold down the Command (Apple) and Option keys until you see the dialog box, "Are you sure you want to rebuild the desktop file?" Click Okay.

Step 3

Once you have determined everything is working normally, you can go back to the Extensions Manager and turn on all the extensions you usually use.

Step 4

You need to restart to have the reactivated extensions load.
