Files with the ".sda" and ".lnx" suffixes means that the file
has been archived. So inorder to be able to execute those file
you need to extract/dissolve the archive files.
 
".lnx"
This means that the file has been lynxed. So you need to get the
LYNX archiver in order to dissolve it. It is available in
most of the FTP site and in Q-link.   
 
".arc"   (another popular archive format)
This means that the file has been ARCed. So you need to get the
ARC archiver in order to dissolve it. It is available in
most of the FTP site and in Q-link.
 
".sda"
This file has been archived in a special way that you don't need
any other program to extract the original files, hence it is called
Self-Dissolving-Archive. Just load it and run it as though it were
a BASIC program and run it; it will do the extraction by itself.
 
Well, I hope this answers your question.
