You experience problems using a document from a DOS or Windows computer.
If you can’t open a DOS document using a Macintosh application, try the following:
m Open the document from within the application by choosing Open in the application’s File menu.
m Use the PC Exchange control panel to specify which Macintosh application will open the document.
(To find PC Exchange, choose Control Panels in the Apple [K] menu.) 
If a DOS document is displayed incorrectly, or you see strange codes or characters in the document,
try one of the following:
m Your application program may have special procedures for opening and saving documents with
different file formats. See the information that came with your application, or call the application’s
publisher.
m Try opening the document in another application.
Note:  Some characters that can be displayed on the Macintosh are not accurately displayed on DOS
computers. 
For information about working with DOS or Windows documents on your Macintosh, see Mac OS
Guide, available in the Guide (h) menu.
A file can’t be thrown away.
m The file may be locked. Select the file’s icon, choose Get Info from the File menu, and click the
Locked checkbox to remove the X. You can delete locked files that are in the Trash by holding down
the Option key while you choose Empty Trash from the Special menu.
m An application program may be using the file. Close the file or quit the application.
m If the file is on a floppy disk, the disk may be locked. Unlock the disk by sliding the tab so that it
covers the hole at the corner of the disk.
m The file may be in a shared folder that can’t be changed. You can throw away the file by turning off
file sharing temporarily (click Stop in the Sharing Setup control panel). Or you can select the shared
folder, choose Sharing from the File menu, and click the box labeled either “Can’t be moved,
renamed, or deleted” or “Same as enclosing folder” to remove the X.
