What is a CDX file?
A CDX file contains an index of files or other data stored in a database. It is similar to a compact index (.IDX) file, but the leaf nodes at the lowest level of a compound index point to one of the tags in the index. CDX files were introduced in version 2 of Microsoft Visual FoxPro, which is a database management program for Windows.
The compound index is the native database index format used by Visual FoxPro. There are two types of CDX files:
Cdf File Reader Software
- Structural CDX file - Automatically opened and maintained by Visual FoxPro when the table is accessed and requires exclusive use of the table.
- Non-structural CDX file - Not opened or maintained automatically by Visual FoxPro when the table is accessed and new records are added but does not require exclusive use of the table.
NOTE: Visual FoxPro was discontinued in 2007.

.CDX File Association 3
A CDX file is an index file utilized by Alpha Five, an IDE for web application developers. It contains table index data referenced by Alpha Five to find table records and is created when index fields in the table are defined and intended to order lists in your data file. CDX files can only hold index names up to ten characters long with no spacing and are similar to .DDX, .ALX, and .ASX Alpha Five index files.
When backing up your data, verify that the CDX file is being saved as well. Otherwise, when the .DBF and .FPT file data is only restored, the CDX file will hold lists from old data and Alpha Five will have to create new lists for the restored data, which may take time.
NOTE: In 2013, Alpha Five became Alpha Anywhere.
[Name of your table].cdx - When a table is created and the index field is defined, the CDX file will be created with the same name as your table.
