File Associations

Computers use file associations to "tell" specific programs to open certain types of files. For example, Adobe Reader is used to open files that end in ".pdf". But sometimes the wrong program tries to open a file. When this happens, you'll need to reset the file association for that type of file.

If you're using a Windows computer, right-click on the file. A menu will appear. Go to Open With. If you see the program in the list, click once on it and the file will open. If you don't see the program, click Choose Program. A window will open with a list of programs. Click once on the program you want and click OK. The file will open.

If you're using a Macintosh computer, click once on the file and press the Command key and the i key together. Under Open With, use the menu to select the program you want to use. Close the window and click twice on the file to open it.
