ARCHIVED: In Mac OS X, how do I assign an application to open certain file types?
Mac OS X allows you to choose which application is
assigned to open certain file types with common filename extensions
(e.g., .pdf
, .jpg
, .tiff
,
.mp3
, .mov
). This is useful, for example, if
you want a file with the extension .pdf
to open with
Adobe Reader instead of the Preview application. Files
created in the Classic environment, which often do not have
a filename extension, can also be assigned to open with an appropriate
Mac OS X application using the following instructions.
Note: The instructions below, which change the file's icon in the Mac OS X Finder to reflect the program that will open it, will have no effect on the type or creator codes which may be contained in the file itself.
- Select the file in the Finder by clicking it once.
- From the menu, select .
- In the
Info
window, click the triangle next to "Open with:" to expand that section of the window. - From the pull-down menu that appears, select the application you
wish to use to open the file.
Note: Not every application listed will open the file as expected. Make sure the application is appropriate for the type of file with which you are working.
To change the application to open all similar file types, click
. You will see a confirmation dialog box asking if this is really what you want to do. Click .
