Question about CDX indexe files #81

Closed dprutean closed 9 months ago

dprutean commented 3 years ago

I am not experienced with DBF, but I got a task to look at the CDX files. Do these files contains relevant data? Can the driver read these files?

albfernandez commented 3 years ago

The cdx files are indexes to speed reading and searching into the main dbf file

I add another url where it explains the same but in a visually cleaner way: https://docs.microsoft.com/en-us/previous-versions/visualstudio/foxpro/s8tb8f47(v=vs.80) https://docs.microsoft.com/en-us/previous-versions/visualstudio/foxpro/k35b9hs2(v=vs.71)

I hope it doesn't bother @albfernandez, I have found on github the code to implement the cdx indices. Currently I am trying, if I succeed I share it with everyone. https://github.com/Chessforeva/JavaFoxDBF/blob/master/cdx.java

Working with DBF and CDX indices I am also interested in the driver supporting the FoxPro Standard TAG CDX index XHarbour Development in Delphi
