Open...

▪ Open brings up a dialog box to open an existing notebook.
▪ To open a notebook:

1. Choose Open from the File menu.
2. In the list box that appears, look for the file you want to open.
3. Click the name of the file, then click the Open button or double-click the name of the file.

▪ By default, Mathematica shows only the files that it knows exactly how to open.
▪ See: Open Special for how to open other file types.
▪ When you try to open a pre-3.0 Version notebook, you can convert the notebook into a Version 3.0 format. Several conversion options are available.
Important: Check that you have write permission in the directory where you are converting the notebooks. Otherwise Mathematica will not be able to convert the files.

▪ Keyboard shortcuts: o ; o o

Mathematica understands the following file types:

▪ TEXT
Files in plain text from any word processor are opened with all the text in a single active initialization cell. When all the text appears on one line, you may want to switch the cell's style to "Text" style, which is normally a word-wrapping style.
▪ Scrapbook (Macintosh)
Files from the Scrapbook open as notebooks containing all the PICT, TEXT, and SND (sound) objects in the scrap file. Note that you can't save the resulting file in Scrapbook form.
▪ PICT (Macintosh)
Files from most graphics programs saved in PICT format open as a single cell containing the picture in the file.
▪ EPSF
Encapsulated PostScript files open as notebooks containing a single graphics cell. For a file originally produced by Mathematica, the resulting cell is identical to the one that produced the file. For a file produced by another program, the PostScript may require some manual editing before it can be rendered or printed.
▪ QuickTime (Macintosh)
QuickTime movies are opened as a QuickTime cell.
