how to create a reader for an unknow file
-
hello i want to create an application who can read me a file who can't be read by any other application that i know, but i know that this file is a data base file and i have and idea of the original extesion of the data base . for more information,this file(the data base) can be opened by one application that i losed it . and i want to know i can to create an application who can read me this file?
Did you expect a serious answer to this question ? You're asking for a program that by extension can magically read any file format that exists now and in the future. If a program can magically work out a file format by itself, why not all of them ? Christian I have drunk the cool-aid and found it wan and bitter. - Chris Maunder

you don't understand what i want. i have database file with unknow extension (maybe *.dbf,*.dbs......)and i want to make a program who can open this file . i am sure that's this file is a database file i won't to make a program who rean any file who can find , i want a program just for this file . like for the files imported from 3Dmax and who can be used with vc++ or other programming language there are a part of code who can read this file . i hope that you understand what i want to do .

You can open and view nearly every file with the Hex Editor available here[^]. The problem will be in interpreting what you see. Each DBMS uses its own internal storage format, and no tool I've found can identify and read them all. You may, with much patience, be able to reverse engineer the file structure from the hex and ascii representation obtainable with the above program, but it's going to be very tedious.

Writing a program that reads a database format without knowing the format isn't really any harder than writing a program that reads ALL unknown file formats. Both require magic. aguest wrote: i hope that you understand what i want to do . Yeah, I do. As someone else said, you can read it in a hex editor, but you can't write code to read the file format, unless you know what it is. Unless you can point an OLEDB driver at it or something, if it's a format you already have a driver for. Christian I have drunk the cool-aid and found it wan and bitter. - Chris Maunder

Hex Editor, yeah they are good, they open anything... anything.:)

Well, I actually found one that this program can't open. It was an Access .mdb, but it may be due to security settings. It also choked on a .asp file, but that one was on an active server and probably couldn't be opened exclusively.:-O Will Build Nuclear Missile For Food - No Target Too Small
