BTX file extension - SEEDIS index file
What is btx file? How to open btx files?
File type specification:
The BTX file extension is associated with the SEEDIS. It is used for index files. It is obsolete product.
The BTXMAKE makes a b+tree file from the SEEDIS style DDF or EDF files for use in the SEEDIS programs. The resultant output file, which has the extension *.btx, replaces the DDX or EDX file and has the advantage of speedier look-up in those programs using data definition files.
The BTX file does not have data stored in it but rather points to records in the DDF/EDF files.
