Apple Power Macintosh 4400 - Manual (Page 104)

You see a message that your computer doesn’t have enough memory to start an
application or open a document.
You can make more memory available to run your application following the
instructions in “Increasing Memory Available to Run Applications” under
“Working With Several Applications at a Time” in Chapter 4 of this manual.
You can’t open a document, or you see a message that an application program can’t
be found.
m Some documents can be opened by more than one application program.
Start a program that you think might be able to open the document. Then
choose Open from the program’s File menu to try to open the document.
m Purchase and install the correct software to use the document, or find out
if the creator of the document can convert it to a form that one of your
programs can use.
m Don’t try to open the files in your System Folder. Most of the files in your
System Folder are used by your computer for internal purposes and are not
intended to be opened.
m Rebuild your desktop. See “Rebuild Your Desktop” under “When You Run
Into Trouble,” earlier in this chapter, for more information.
m If the document was created on a PC (personal computer running DOS or
Windows), use the PC Exchange control panel to specify which Macintosh
program will open the document. For information about working with
DOS documents on your Macintosh, see the information about DOS in
Macintosh Guide, available in the Guide (h) menu.
You experience problems using a document created on a computer running DOS
or Windows.
If you can’t open a DOS document using a Macintosh program, try
the following:
m Open the document from within the program by choosing Open in the
program’s File menu.
m Use the PC Exchange control panel to change the document’s type to one
that can be opened by the program.
