Chemical information file created by ChemDraw, a molecule editing program suite for Macintosh and Windows platforms; stores molecular data in a tagged binary format; used for storing accurate chemical drawings.
CDX files store information such as atoms, bonds, fragments, arrows, and text.
The CDX format is the native format used by ChemDraw. Another format called CDXML (.CDXML files) is used for exporting and exchanging CDX data in an XML format.
XML diagram file created by ConceptDraw PRO, a technical drawing program; stores the XML version of a binary .CDD file; used for transferring drawing information in an XML exchange format, which is easier to read than the binary version.
File created by CorelDRAW, a vector-graphics editing program included with the CorelDRAW Graphics Suite software package; contains a compressed .CDR drawing file; used to reduce the storage space required for a drawing.
CDX files are useful for sending smaller files over email, or for archiving drawings on external media.
Index file utilized by Alpha Five, an IDE for Web application developers; contains table index data referenced by Alpha Five to find table records; created when index fields in the table are defined and intended to order lists in your data file; can only hold index names up to ten characters long with no spacing; 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.
Common CDX Filenames:
[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.
