READ ONLY FILE
A read only file, as the name implies, is a file whose contents can be only read but cannot be written into. In other words, you can view the contents of a read only file but cannot change or make modifications to that file. Of course, a read only file is not a protected file but one which cannot be written into. You can make changes and modifications to a read only file but the same cannot be saved in the same file name. For example, if you have a file name test.xls and you have made it a read only file, then changes can be made to that file but the same cannot be saved under the name test.xls but can be saved with an another name.

SAVING A READ ONLY FILE
As already pointed out, read only files cannot be saved in the original name and they must be saved in an another name. So follow the steps below to save a read only file

1. Go to FILE->SAVE AS (The save as dialog box would be displayed)
   
2. Now select the path where you want to save the file from the LOOK IN box.
3. Now type a file name in the FILE NAME box below
4. SAVE the file by clicking the SAVE button.

• The above steps holds good for almost all applications.
• If you want to save the read only file in its original name, then save the file in another name, delete the original file and rename the newly created file.
