title: How to open SDF file
body: <p>So I am aware that typically an SDF file would be thought to be a SQL Server Compact Database file.  However it is highly unlikely that is the case here.</p>
  
  <p>I have a client that is trying to pull their data out of a legacy system.  I've been given access to the data files and some go back as far as 1998. According to this:</p>
  
  <p><a href="http://fileinfo.com/extension/sdf" rel="nofollow">http://fileinfo.com/extension/sdf</a></p>
  
  <p>these files are likely Standard Data Files.  This makes sense based on the naming of the files as well. Each file name appears to be what I would normally consider a table name. My understanding is that a SQL Server Compact Database would have all of these tables in a single file.</p>
  
  <p>So the question now is what system can read these SDF files.  What late 90s database programs would use SDF files?  I've tried Googling this and it doesn't look like there is much on the topic. </p>
