dtf Files

[lloydin]

I have some old data dating back to late 80's, early 90's with the file extensions as follows;
.dtf data file
.idx this file automatically came up when I saved a .dtf document
I do not remember which program used these files and it is long gone.
Can U help?
Thanks

Hi there!
I am not 100% sure but i think is Q&A.

They sound like the "old style" data files you used to have that have an external index file (.idx). I'm not exactly sure which file system they would belong to but you I suppose you have a couple of problems:

1) What is on the files
2) What are the displacements of the fields
3) Are there any unusual field types in there like compressed fields and such like

You might find that there is an "unload" utility that allows you to dump the contents out to ascii for you to put into another database system. That could be tricky if you're missing software however...

You might be able to establish a connection to the files via jet or odbc but you might need some kind of DDF/DSN to be set up first - and that could prove difficult if you don't know the layouts and software is missing and so on...

You could try using VB Open statement to open the files as sequential, random or binary and then try to dump the stuff out to ascii - again you'll need to know what the file layouts are for this to work any you may come up against problems if there are unusual field types in there.

Sorry I couldn't be more help...
