How to change file association?

[yuy]

Can anybody tell me how to change the default application with certain files?

e.g. I want to change the default opener of pdf to Acrobat reader rather than preview.

Thanks in advance.

Get info on a .pdf, change "open with" to Acrobat reader, click "change all"
