How can I open DBX, DBI, DCX adn DBM files?

I’ve a database – three folders with a bunch of file formats: DBX, DBI, DCX and DBM files, nothing more. What is open – no idea. I’ve tried to use Visual FoxPro, but it needs files in DBC format. Tried to use DBXtract but that was something strange and incomprehensible to use and produces different errors, perhaps because I have Vista x64 and the program just under another bit. I don’t know what to do and how to access the database. The files weigh in at gigabytes. Can you suggest what I need to read these formats? Or else, are there methods to open the entire contents?

    This may be a DataEase database:

    Hope this helps.

    Unfortunately, the Microsoft way of identifying files by their extensions alone does not help us here since each of the file extensions listed above were used by multiple programs. Your best bet is to download the file utility from SourceForge, install it and run it against each of these files to find out if it can determine what type of file it is (and the program you can use to open it). The file utility does not care about the extensions (or even if there is one). It looks for "magic numbers" - identifying markers - inside of the file to determine what type of file it is or what program created it.

    DBX is most commonly associated with Outlook Express, but there are at least 2 other file types that have used the extension.

    The last time I saw a DBM file was back when I was writing programs in dBASE III and the Clipper compiler which used DBF files for the database itself and associated memo fields (varying length text fields) were stored in an associated DBM file.

    DBX is used by Visual Fox Pro (and by Outlook Express, but this is clearly not the case here). According to, the other extensions are as follows:

    DBI - Borland Database Explorer or ISearch (an old text retrieval system)
    DCX - primarily Graphics Multipage PCX
    DBM - DAZ 3D DAZ Studio 4 and ColdFusion Server

    What this all adds up to, in my opinion, is that someone used their own made up extensions rather than stick with the standard ones. You may be able to learn more by opening the files with a hex editor and looking at the content. Often the application name is written near the beginning of the file (or sometimes near the end), and you'll also find out whether it's a text file (some readable text) or binary/image (all gobbledigook).
