How to save Older Mathematica Files With The .ma Extension.
In order to use them I needed to convert some older (1995) mathematica files I found in a CD in a used book so that they would run on 11.1. They had extension ".ma".
To do this I did the following.
- Download the Mathematica CDF program. To find this look under resources in the Mathematica start window.
- Place the files to be modified in a there own directory.
- Change windows folder options to show all extensions.
- Change the ma extension to nb. With my ".ma" files if I did not do this CDF would not read them.
- Read the files into the CDF program.
- In the edit drop down choose Select All then Copy.
- Open a new notebook in Mathematica and paste the text into.
- Save the file. I added the word reworked at the end of the filename but before the extension. Example Chpt1.ma-->Chpt1.nb->>into CDF->>copied text to new file in Mathematica --> saved as Chpt1reworked.nb.
There maybe problems as some instructions have changed, but this will get you started.
Good Luck
