This tells how I saved some older Mathematica files with the .ma extension.
I found some older (1995) mathematica files in a CD in a used book. They had extension '.ma'. To use them I needed to convert them so that they would be recognized by V11.1.
To do this I did the following.
- Download the Mathematica CDF program. To find this look under resources in the Mathematica start-up window.
- Place the files to be modified in a their own directory.
- Change Windows folder options to show all extensions.
- Change the .ma extension to nb. If I did not do this CDF would not read them.
- Read the files into the CDF program.
- In the Edit drop menu down, choose Select All then Copy.
- Open a new notebook in Mathematica and paste the text into it.
- Save the file. I added the word 'reworked' to 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 the reworked notebooks in V11 as some Mathematica have changed, but this will get you started.
