Function IndexExt() Foundation
Returns the default extension for index file names.
IndexExt() --> cExtension
The return value of IndexExt() depends on the database engine (DBE) managing the files in the work area. When the DBFNTX DBE is being used, IndexExt() returns the character string ".NTX". For another DBE, a character string containing the default extension for index file names under that DBE is returned.
The function IndexExt() exists for compatibility reasons. The function OrdBagExt() should be used instead of IndexExt().
IndexExt() determines the default extension for index files. This allows checking for the existence of an index file without knowing which database engine will manage the index file.
