As far as the program goes - just re-install the Adagio module - it's way better than trying to copy in individual files.

Adagio Ledger data files all begin "GL" and have the extension you selected when the data was created. The most important files are:

• GLDATA.xxx
• GLPST.xxx
• GLGLOB.xxx
  

There are lots of others, but with these it would be possible to rebuild an incomplete set.
