Encryption

I encrypted files using Norton 20yrs ago to save space.  The file is under the folder N360_Backup\....  How do I decrypt? 

Thanks for responding. Extract is not an option when i right click in windows file manager. I don't recall what norton product I used, it was so long ago. 

What Norton product did you use to encrypt these files? It is possible that you might need that product to be able to decrypt if it used proprietary encryption methods.

Have you tried using Windows Explorer's right click menu to see if you can Extract the files?
