Powerflex Database File extentions -

-

i trying understand different file extensions pfxplus powerflex database. please telling me briefly each file for?

.k1
.k2
.k3
...
.k13
.k14
.k15
.fd
.def
.hdr
.prc
.pc3

data files:

ok, .dat data file. .k1 -> .k15 index files.

these critical data files runtime. (combined filelist.cfg or pffiles.tab similar define files available overall).

.fd file definition, needed compiling programs .tag (which did not mention) needed if need access field names @ run time (such using generic report tool) .def file definition in human readable form, , not needed process produced programmer or user can understand file structure.

run time:

the .ptc files compiled threads interpreted powerflex runtime.

the .prc file resource file used @ runtime in conjunction .ptc file - defines how character based program in gui environment in "g-mode". cheap way upgrade character based programs when windows first started getting popular usage.

.hdr , .pc3 escape me @ moment, vaguely familiar - .hdr data file used compression or special field types later versions of pfxplus. .pc3 may in fact .ptc files...
