Information about the .mdx (mdx) file type

This is one of two possibilities that we have on file for the .mdx file extension, follow this link to view both possibilities.

Below is all the information we have available on file about the .mdx (mdx) file type.

.mdx
dBase index file. Each .mdx file will normally be paired with a .dbf file with the same name (but it does not follow that all .dbf flies will have an acompanying .mdx file.)

A .mdx file may be referred to as a "multiple index file".

.mdx files were first used by dBase IV, and replaced the use of .ndx files used in earlier versions of the database. .mdx files are maintained and updated automatically by dBase (whereas the older .ndx files had to be manually maintained by issuing a REINDEX command.)

Where this is available we would like to include file format information on .mdx files, as well as information on how to view or open files of type .mdx. If you know of any information which we have missed then please let us know.
